This file contains release notes for TECOC. The "base version"
|
||||
is 100 (reported by the EO command). The version number starts at 100 to
|
||||
avoid confusion with TECO-11 version numbers, which were close to 40 as of
|
||||
01-Jan-1987.
|
||||
|
||||
|
||||
10-Dec-1987 version 100
|
||||
|
||||
baseline version as of Fall Decus Symposium, Anaheim

|
||||
|
||||
1. created this file
|
||||
2. changed EXEEO.C to make the version number 101.

initialized to 1 in DBGDSP.C.
|
||||
10. Added semi-colon to line 181 of ZOPINP.C so it'll compile.
|

|
||||
12. Added code to set TrmTyp in XENIX section of ZTRMNL.C.

"65536" to "65535" in ZRDLIN.C.
|
||||
14. fixed control-C handling, so that type-out of a large buffer works.
|
||||
Changed EXECST.C, ZDSPBF.C, FRSTCH.C, READCS.C.
|
||||
15. added a test to EXECST.C so that commands like "<test$$" will
|
||||
now produce "unterminated command" errors, as they should
|
||||
16. modified EXEEI.C to make EI$$ a null command to make CHANGE.TEC work
|

31-Mar-1988 version 104
|
||||
|
||||
1. changed EXEEO.C to make the version number 104.

had to be changed: many files modified. Also changed macros that
|
||||
are in CHRMACS.H to use an array. Merged that array with the one that
|
||||
was in ReadCS.
|
||||

|
||||
11. overhauled error reporting. Many modules changed, including all "Z" files.
|
||||

|
||||
12. Replaced GroEBf with InsStr to merge several copies of the same code
|
||||
sequence. Affected ExeBSl, ExeCtI, ExeG, ExeI, Replac.
|
||||
13. Removed post-copy of memory after ZRaloc calls. ZRaloc does it.
|
||||
14. Took /STANDARD=PORTABLE off VMS compile commands to prevent warnings
|

|
||||
|
||||
|
||||
30-Jul-1988 version 106

|
||||
|
||||
1. changed EXEEO.C to make the version number 107.
|
||||
2. fixed FR command.
|
||||
3. fixed it so two control-C's terminate TECOC, as it should be.
|
||||
4. overhauled command-line parsing to make it use a TECO macro to do it,
|
||||
like TECO-11 does. Major changes to initialization code. I did this to
|
||||
provide the extra power and to make invocation of TECOC the same as TECO-11
|
||||
under VAX/VMS. Created ExeEG, ZExeEJ, ZEgIni, ZEgLib, ZEgMem, ZEgSym
|
||||
and ZEgVte. Deleted ZIniFl, Mung, ZExeEG.
|
||||
5. fixed ::S command.
|
||||
6. fixed ] command's memory deallocation.
|
||||
|
||||
|
||||
22-Feb-1989 version 108 ( porting to Turbo C )
|
||||
|
||||
1. changed EXEEO.C to make the version number 108.
|
||||
2. created function prototypes (without arguments) in DefTeco.h and removed
|
||||
them from all other files.
|
||||
3. changed /REPLACE to /INSERT in ZVBLD.COM
|
||||
4. fixed definition of ErrTxt in BldStr.
|
||||
5. moved "#include stsdef" into VAX section of ZErMsg.
|
||||
6. moved expressions out of "if" statements to avoid compiler warnings in
|
||||
FindQR, MakDBf, PshMac, StCopy, ZTrmnl.
|
||||
7. Deleted reference to ZDefErr.h from ZOClDe.
|
||||
8. deleted ZError.h
|
||||
9. changed "ErrMag" to "ErrMsg" in ZOClos.
|
||||
10. removed variables declared but never used in DoEI, ExeEG, WrBufr, ZOClos.
|
||||
11. removed "return(xxx)" from XENIX section of ZHhelp, which is a VOID
|
||||
function.
|
||||
12. Express 32768 in octal in DefTeco.h for ET_TRAP_CTRL_C to avoid problems
|
||||
putting it into an unsigned EtFlag.
|
||||
13. Added type-cast to ZCpyBl call in RdLine.
|
||||
14. changed XENIX section of ZExeEJ so it defines ZExeEJ, not ZExCtH.
|
||||
15. Replaced the Execut function with syntax for calling a function whose
|
||||
address you have in a variable.
|
||||
16. Made mods to make it run under Turbo C under MS-DOS. Added __TURBOC__
|
||||
sections to Zxxxx.c files and created ZPBLD.BAT and ZPDBLD.BAT.
|
||||
19. Fixed Turbo C section in ZDspBf, ZDspCh, ZChIn, ZWrite.
|
||||
20. Changed "LONG" to "ptrdiff_t" in several files.
|
||||
21. Added Turbo C section to ZPrsCL.
|
||||
Just to get it working, commented out the Turbo C code in ZPrsCL.
|
||||
This prevents the command-line macro from executing, which avoids the
|
||||
execution of EJ and EG commands in the macro. EJ and EG are not yet
|
||||
supported for non-VMS environments. It now limps under Turbo C/MS-DOS
|
||||
|
||||
|
||||
28-Feb-1989 version 109 ( more porting to Turbo C )
|
||||
|
||||
1. changed EXEEO.C to make the version number 109.
|
||||
2. made type conversions explicit via type casts in various functions.
|
||||
3. replaced calls to ZChrIt with type-cast "(char)" and deleted ZChrIt
|
||||
4. appended all the Dbgxxx functions to the end of TECOC.C and changed
|
||||
compile/link so there is no separate debugging library. This simplifies
|
||||
the link sequence.
|
||||
5. fixed VDOW.C and VSETW.C so setting DEBUGGING to NO will not cause
|
||||
compilation errors.
|
||||
6. changed references to .h files to lowercase so you don't have to
|
||||
explicitly rename them after copying them from one machine to another
|
||||
7. various minor changes so it will build for an UNKNOWN environment
|
||||
8. use FILENAME_MAX, an ANSI C identifier
|
||||
9. changed the XENIX identifier to the more general __UNIX__ and restructured
|
||||
the conditional compilation code to use "#elif".
|
||||
10. replaced StCopy with strcpy
|
||||
11. replaced ZCpyBl with MEMMOVE
|
||||
12. created a file named MAKEFILE for use with Unix "make".
|
||||
13. improved type definitions and casting to keep lint happy.
|
||||
14. use EXIT_FAILURE and EXIT_SUCCESS in calls to exit() and ZAbort().
|
||||
15. Defined return codes for the EJ command in systems other than VMS
|
||||
so the command-line parsing macro could function.
|
||||
16. Removed references to StCopy and ZCpyBl from ZPBLD.BAT and deleted
|
||||
ZPLNK.BAT. Fixed ZPLNK.BAT to not refer to DBGTECOC.LIB.
|
||||
|
||||
|
||||
28-Feb-1989 version 110
|
||||
|
||||
1. changed EXEEO.C to make the version number 110.
|
||||
2. made the 2048 bit of the ET flag cause the BACKSPACE character to be
|
||||
treated just like the DEL character on input. This supports the
|
||||
conventions used by IBM PCs and Unix. On those systems, you'll have
|
||||
trouble getting a BACKSPACE into the command line, a minor problem.
|
||||
3. to simplify an effort to port TECO-C to RT-11, renamed the following
|
||||
files so the name portion of the filespec is 6 characters or less.
|
||||
|
||||
renamed CHRMACS.H to CHMACS.H
|
||||
renamed COMMANDS.TXT to WCHART.TXT
|
||||
renamed DEFCHARS.H to DCHARS.H
|
||||
renamed DEFSCREN.H to DSCREN.H
|
||||
renamed DEFTECO.H to TECOC.H
|
||||
renamed TEC0_V40.TEC to TECV40.TEC
|
||||
renamed TECO_V40.TES to TECV40.TES
|
||||
|
||||
The following files were not renamed, and are the only remaining files
|
||||
with names longer than 6 characters.
|
||||
|
||||
AAAREADME.TXT I just didn't want to rename this one
|
||||
GETTECO. used only on Unix systems
|
||||
MAKEFILE. used only on Unix systems
|
||||
PROBLEMS.TXT I just didn't want to rename this one
|
||||
RELEASE.TXT I just didn't want to rename this one
|
||||
ZVLOGIN.COM used only on VAX/VMS systems
|
||||
ZXAFTER.CSH used only on Xenix systems
|
||||
ZXLOGIN.CSH used only on Xenix systems
|
||||
|
||||
4. Fixed ZPBLD.BAT: removed superfluous -I option, added ECHO statements so
|
||||
you can tell how far it's gotten, lowercased file names.
|
||||
5. Removed definition of TraceM from ZExCtC, which doesn't use TraceM.
|
||||
6. Don't return a value from ZDoCmd or ZHelp, they're VOID functions.
|
||||
7. Fixed Sun and Turbo C sections of ZExeEJ and ZClnEG.
|
||||
8. Changed second argument of PushEx from BYTE to DEFAULT.
|
||||
9. Made ZClnEG a LONG function to match it's use in ExeEG.
|
||||
10. Made MakDBf calls in PushEx and GetNMA use a type cast when passing
|
||||
EstTop and EstBot so it works under Turbo C.
|
||||
12. Fixed expression syntax in CLPARS.TES.
|
||||
13. Fixed handling of :ER commands in Turbo C section of ZOpInp.
|
||||
14. Added function prototypes to tecoc.h. They're conditionally compiled
|
||||
based on the new USE_PROTOTYPES identifier defined in zport.h.
|
||||
15. Replaced GENCLP.TEC with GENCLP.C.
|
||||
|
||||
|
||||
11-Jun-1989 version 111
|
||||
|
||||
1. changed EXEEO.C to make the version number 111.
|
||||
2. More type-casts added to allow Turbo C to compile the code when the
|
||||
function prototypes are used (USE_PROTOTYPE == YES).
|
||||
3. Moved setting of EtFlag out of ZInit.c and into ZTrmnl.c.
|
||||
|
||||
28-Jun-1989 version 112
|
||||
|
||||
1. changed EXEEO.C to make the version number 112.
|
||||
2. changed || to | in ZTrmnl.c to fix setting of EtFlag.
|
||||
3. changed CrType to VT100 in ZTrmnl.c for IBM-PC so ANSI sequences are used.
|
||||
4. rewrote logic to fix bugs and improve readability in InpDel.c.
|
||||
5. renamed ScrnOp to ZScrOp so IBM-PC screen handling could be added.
|
||||
6. replaced old usage of ET_BKSP_IS_DEL with new code in ZChIn.
|
||||
7. added error message generation to ZChIn
|
||||
8. fixed ZVBLD.COM so the link of GENCLP has LNK$LIBRARY defined
|
||||
9. changed mktemp to tmpnam (ANSI) in ZOpOut.c.
|
||||
10. merged VDoW, VGetW and VSetW into ExeW
|
||||
11. Lots of little changes to reduce messages produced by lint and by
|
||||
Turbo C when the -w switch (maximum warnings) is used.
|
||||
|
||||
19-Jul-1989 version 113
|
||||
|
||||
1. changed EXEEO.C to make the version number 113.
|
||||
2. Fixed ZPBLD.BAT and ZPTLIB.BAT

5. Fixed comments in FindQR and tecoc
|
||||
6. Changed ugly \015 to \r, \012 to \n, \011 to \t in all files
|
||||
7. More type casting to reduce warnings from Turbo C.
|
||||
8. Changed almost every file to insert new "charptr" and "QRptr" types.
|
||||
These are needed to support the brain-damaged memory access on IBM-PCs,
|
||||
where the pointers need to be "HUGE" to work.
|
||||
9. fixed a bug in MakRom that caused :X commands (among others) to fail.
|
||||
10. Converted QBfBeg, QBfPtr and QNumbr to the simpler QR
|
||||

|
||||
Turbo C sections.
|
||||
14. made 0EJ return 0 for Turbo C.
|
||||
15. Fixed ZWrite code for Turbo C.
|
||||
|
||||
02-Aug-1989 version 114
|
||||
|
||||
1. changed EXEEO.C to make the version number 114.
|
||||
2. Renamed RELEASE.TXT to CHANGES.TXT
|
||||
3. merged all the Z files into ZVMS,C, ZMSDOS.C, ZUNIX.C, ZUNKN.C
|
||||
4. merged all the SKP files into SKPCMD.C
|
||||

|
||||
6. merged REDUCE.C into PUSHEX.C
|
||||

|
||||
8. merged DOEI.C into EXEEI.C
|
||||
9. merged DOFBFC.C into SRCLOP.C
|
||||
10. merged EXEE*.C files into EXEE.C (EXEEB.C is an exception)
|
||||
11. merged EXEF*.C files into EXEF.C (EXEFB.C is an exception)
|
||||
12. Implemented colon modifier on EW command. This is an undocumented
|
||||
feature required for the CLPARS macro to work on non-VAXen.
|
||||
13. merged ZFILES.H into ZVMS.C, ZMSDOS.C, ZUNIX.C
|
||||
14. fixed GENCLP.C yet again, for VMS
|
||||
15. fixed memory shuffling bug in RDLINE.C
|
||||
|
||||
21-Aug-1989 version 115 (Manfred Siemsen)
|
||||
|
||||
1. Changed ExeEO() in EXEE.C to make the version number 115
|
||||
2. Created DEFEXT.H, replaced all EXTERN lines with #include "defext.h"
|
||||
3. Modified all #if DEBUGGING...#endif lines to call 3 debugging
|
||||
functions: DbgFEn() upon function entry, DbgFEx() upon function
|
||||
exit, and DbgFMs() for messages in the body of a function. Also,
|
||||
indented the debugging lines so they line up under the code they
|
||||
"belong" with, instead of being munched over on the left margin.
|
||||
4. Modified debugging routines to use sprintf/printf to display
|
||||
values of variables instead of displaying things "manually" through
|
||||
other Teco-C build/display routines. We still avoid the use of
|
||||
sprint/printf in non-debugging code.
|
||||
5. Modified the indentation scheme to more closely match K&R
|
||||
6. Put squiggly braces '{}' around ALL statements, even if they
|
||||
aren't required.
|
||||
7. Modified the comment scheme to be consistent with Pete's
|
||||
latest X-window'ish standard.
|
||||
8. Created a Turbo C MAKEFILE (MAKEFILE.TC).
|
||||
9. Began implementation of ZPWild() and ZSWild() in ZMSDOS.C. It
|
||||
seems to work ok, but there should be more error checking put in
|
||||
to guard against the user entering a bizarre filename.
|
||||
10 Implememted ZDoCmd() in ZMSDOS.C. Required change to ExeEG() in
|
||||
EXEE.C. If it wasn't :EG, TxtLen was never set, might have been
|
||||
garbage, moved TxtLen assignment out of "if (COLON..." statement.
|
||||
Also, ZAbort() was called if TxtLen was not zero, should have
|
||||
been called if TxtLen *is* zero.
|
||||
|
||||
30-Aug-1989 version 116
|
||||
|
||||
1. Changed ExeEO() in EXEE.C to make the version number 116
|
||||
2. rearranged includes in "Z" files so that my .h files come after the
|
||||
system ones. This was needed so ZPORT.H can redefine FILENAME_MAX,
|
||||
which on VMS is wrong (38 ain't right). Rearranged ZPORT.H for the
|
||||
same reason.
|
||||
3. Replaced ERRMSG.C with ERR.C and created the new error reporting
|
||||
functions ErrChr and ErrStr. Doing this removes places where I was
|
||||
writing into string literals, which worked but wasn't real kosher.
|
||||
It also makes lint happy about ErrMsg (fixed number of arguments now)
|
||||
and modularizes the error code. Merged DSPCHR.C and VRBERR.C into
|
||||
ERR.C.
|
||||
4. Created ZVrbos.
|
||||
5. Fixed error message numbering.
|
||||
6. Fixed prototype for ErrDsp and ErrPst in ERR.C.
|
||||
7. Commented out illegal test case in TSTQR.TEC.
|
||||
8. Made Charac a char instead of an int in ZChIn to fix bug.
|
||||
|
||||
21-Oct-1989 version 117
|
||||
|
||||
1. Changed ExeEO() in EXEE.C to make the version number 117
|
||||
2. Moved #endif in TECOC.C from just after DbgSlv() to just after
|
||||
DbgDsp() so DbgDsp() wasn't included when DEBUGGING is FALSE.
|
||||
3. Updated MAKEFILE.TC.
|
||||
4. Updated ZPTLIB.BAT.
|
||||
6. Changed prototype of ZVrbos in ZMSDOS.C, ZVMS.C, ZUNIX.C,
|
||||
ZUNKN.C, and TECOC.H.
|
||||
7. Changed DoEI() comment in EXEE.C.
|
||||
8. Made ZRdEI() call ZRdLin() instead of calling fgets() directly.
|
||||
9. Changed ZWrite() to ZWrLin(), it's more descriptive.
|
||||
|
||||
23-Oct-1989 version 118
|
||||
|
||||
1. Changed ExeEO() in EXEE.C to make the version number 118
|
||||
2. minor fixes to make lint happy
|
||||
3. Changed ZChIn() in ZMSDOS.C to ignore any IBM PC scan code
|
||||
other than DEL to eliminate the "Unrecognized character" bomb.
|
||||
4. Changed CLPARS.TES so filespec memory works on PC's.
|
||||
5. Changed EXEQ.C to fix numeric expression parsing
|
||||
6. Change definition of FEArry[] from (*F[])() to (*F[])(VOID)
|
||||
to eliminate Turboc C "function w/no prototype" warning.
|
||||
|
||||
03-Nov-1989 version 119 (Manfred)
|
||||
|
||||
1. Changed ExeEO() in EXEE.C to make the version number 119.
|
||||
|
||||
2. Because of some bizzare behaviour, the CHECKSUM_CODE #define and routines
|
||||
were added to check code at runtime to make sure it wasn't being
|
||||
overwritten. These routines read the Turbo C .MAP file to get the order
|
||||
and length of all the modules, calculates and stores an initial checksum
|
||||
for each module; and then compares the initial checksum of each module
|
||||
with the checksum calculated after every command is executed in ExeCSt().
|
||||
|
||||
3. Changed ZAlloc(), ZRaloc(), and ZFree() to return and expect a new
|
||||
type "voidptr" instead of charptr's. I then removed the casts before
|
||||
ZAlloc() and ZRaloc() returns in the code. Borland Turbo C says that
|
||||
explictly casting returns from malloc/realloc hides things from the
|
||||
compiler and is bad practice in ANSI C.
|
||||
|
||||
4. Changed "struct QReg *LQTabl" to "QRptr LQTabl" in the definition of
|
||||
MStck in TECOC.H per phone call w/Pete.
|
||||
|
||||
5. Changed an incorrect call to DbgFEn() in ZOpOut()...should have displayed
|
||||
DbgSBf instead of "".
|
||||
|
||||
6. Changed the DbgFEn(), DbgFEx(), and DbgFMs() calls to send NULL instead
|
||||
of "" if there is no special debugging message to display. This saves
|
||||
space when Turbo C is not merging duplicate strings (tcc -d). Otherwise
|
||||
there are billions of "" strings in the .EXE file ("" strings take 1
|
||||
byte of space because they contain a '\0'). I used CHANGE.TEC to do it!
|
||||
|
||||
7. Changed ZRaloc() in ZMSDOS.C to manually reallocate blocks. There is a
|
||||
problem with Turbo C's farrealloc() in that it uses movedata() to move
|
||||
data from the old block to the new block. Movedata() expects a size_t
|
||||
as the number of bytes to move. size_t under Turbo C v2 is *always* a
|
||||
16-bit unsigned int regardless of memory model. This means that if the
|
||||
old block is >64K, movedata() won't move the data correctly from the old
|
||||
block to the new block when the old block is >64K.
|
||||
|
||||
8. Implemented the ^B system date (ZExCtB) and ^H system time (ZExCtH)
|
||||
routines in ZMSDOS.C using DOS calls. EIDATE.TES$ will display the
|
||||
current date and time.
|
||||
|
||||
9. Initialized ff_status in ZMSDOS.C to -1 so EN$$ with no preceding
|
||||
ENfilename$$ doesn't blow up by calling findnext() with no initial
|
||||
findfirst(). Is <File Not Found ""> a reasonable return?
|
||||
|
||||
10.Changed ExeRBr() so that End_P1 is set to NULL when Start is set to
|
||||
NULL after the ZFree(QR->Start). Otherwise, End_P1 might not be NULL
|
||||
and will cause problems for those routines which blindly subtract
|
||||
End_P1 from Start to get the length of text in the Q-register.
|
||||
|
||||
11.Changed the line in ^EQq logic part of BldStr() where QR->End_P1 was
|
||||
being subtracted from QR-Start, when it should be the other way around.
|
||||
|
||||
12.Changed FArray[] in ExeCSt(). The ^Q entry was ExeNYI(), it should have
|
||||
been ExeCtQ(). The ^_ entry was ExeOpr(), it should have been ExeUsc().
|
||||
Actually, both ExeOpr() and ExeUsc() would have pushed ^_ on the stack,
|
||||
so it was a...uh...push.
|
||||
|
||||
13.Changed ^G entry FCAray[] in ExeCrt() from ExeNul() to ExeIll() so it
|
||||
jibes with FArray[] in ExeCSt() entry.
|
||||
|
||||
14.The logic in ReadEI() in EXEE.C determining whether or not to add a
|
||||
trailing CR-LF to the line read from the EI file was wrong. ReadEI()
|
||||
now calls ZRdlin() to read lines from the EI file. ZRdLin() returns
|
||||
the length of the read line *without* the trailing newline returned by
|
||||
fgets(). The ReadEI() logic was checking if the line ended in VT or
|
||||
in ESC-CR-LF. Since the line returned by ZRdLin() should never end in
|
||||
CR-LF, the ESC check was bogus. I changed it to only add a CR-LF if
|
||||
the line did NOT end in VT or ESC which I think was the original intent.
|
||||
|
||||
15.While playing with ReadEI() in EXEE.C, I was having problems reading in
|
||||
a huge macro (>ZBFINIT bytes long). The problem was that if the EI
|
||||
buffer became full (ie: BufPtr == ZBfEnd), ReadEI() was calling
|
||||
ZRdLin() with (ZBfEnd-BufPtr == 0). ZRdLin() was in turn essentially
|
||||
calling "fgets(buf,0,fp)". When told to read into a 0 size buffer,
|
||||
fgets() simply returns the buffer. ZRdLin() only fails if fgets()
|
||||
returned NULL or if an error happened, otherwise it will happily
|
||||
return 0 as the length of the line it read, therefore, back in
|
||||
ReadEI(), the "BufPtr += line_len" never incremented BufPtr
|
||||
anywhere and ReadEI() never broke out of it's FOREVER loop, it
|
||||
looped infinitely, reading zero bytes into a zero length buffer.
|
||||
|
||||
I added the ZBFMIN and ZBFEXP #defines in ZPORT.H and changed ReadEI()
|
||||
so it dynamically reallocates the EI buffer when it is close to
|
||||
becoming full.
|
||||
|
||||
16.Changed ExeCtu(). The call to MakRom() used to make the Q-register
|
||||
text area 1 character longer when doing a "n^Qq" was sending the wrong
|
||||
argument. It was sending the new *total* size of the text area
|
||||
(end-start+1) instead of the *additional* size of the text area (1 byte).
|
||||
|
||||
17.Changed the way the CLPARS macro is handled:
|
||||
|
||||
a) If USE_ANSI_CLPARS is FALSE.
|
||||
|
||||
Changed CLPARS.TES to not clear itself out of memory when it was
|
||||
finished. The CLPARS macro is loaded and executed in Q-register Y.
|
||||
The last thing it did was a "0,0XY" to clear itself out. The problem
|
||||
is that ExeX() would call ZFree() to clear Q-register Y, leaving
|
||||
CBfPtr effectively pointing into a free'ed memory area. This wasn't
|
||||
fatal because the "0,0XY" was the very last thing in the CLPARS macro
|
||||
so no further TECO instructions were looked for in the free'ed area;
|
||||
but, technically it was wrong. I removed the "0,0XY" from the CLPARS
|
||||
macro and changed ZPrsCl() so it manually ZFree()'s Q-register Y after
|
||||
it finishes executing it.
|
||||
|
||||
Note: SQU also uses this technique: issuing a '0,0Xq' at the tail end of
|
||||
a macro loaded in Q-register 'q' to clear the macro out after it
|
||||
finishes executing. If this is a common TECO macro practice, maybe
|
||||
we'll have to think this through a little more.
|
||||
|
||||
b) If USE_ANSI_CLPARS is TRUE
|
||||
|
||||
If USE_ANSI_CLPARS is true, the CLPARS macro is stored as one
|
||||
gigantic string in clpars[]. If USE_ANSI_CLPARS is false, the
|
||||
CLPARS macro is split into lines and stored as an array of strings
|
||||
in *clpars[]. The advantage to USE_ANSI_CLPARS is that to execute
|
||||
the CLPARS macro, ZPrsCL() simply made the text area pointers of
|
||||
Q-register Y point at clpars[] to "load" Q-register Y before doing
|
||||
the MY$$. Otherwise, if USE_ANSI_CLPARS is false, the CLPARS
|
||||
macro is executed by (slowly) loading it from *clpars[], line-by-line,
|
||||
into Q-register Y and then doing the "MY$$".
|
||||
|
||||
The problem was that if USE_ANSI_CLPARS was true, Q-register Y held
|
||||
statically allocated data which could cause problems when the CLPARS
|
||||
macro did the "0,0XY" to clean up. "0,0XY" would make ExeX() try to
|
||||
ZFree() the statically allocated clpars[] string.
|
||||
|
||||
While looking at this problem I noticed that, other than for historical
|
||||
reasons, there is no reason the CLPARS macro *has* to be executed from
|
||||
Q-register Y. I changed ZPrsCL() so that if USE_ANSI_CLPRS is true, it
|
||||
directly executes the CLPARS macro from the clpars[] string without
|
||||
bothering to load it into Q-register Y first.
|
||||
|
||||
18.Removed TRACE_IMBEDDED_MACRO.
|
||||
|
||||
19.Removed static initialization of QRgstr[] in TECOC.C and moved it
|
||||
into MemIni() in INIT.C along with the other initializations of
|
||||
global static arrays (QStack[], etc). [See suggestion (1) below]
|
||||
|
||||
20.Changed ExeEO to return ExeNYI() for "nEO".
|
||||
|
||||
21.Changed DoEI(). DoEI() calls PshMac(), ExeCSt(), and PopMac(). If the
|
||||
ExeCSt() failed, it would do a return(FAILURE) without doing the PopMac(),
|
||||
leaving the macro stack off and CBfPtr pointing into the EI buffer. DoEI()
|
||||
was changed so that it does a PopMac() even if ExeCSt() fails. This same
|
||||
type of logic was changed in ExeM().
|
||||
|
||||
This problem didn't appear unless you tried executing a macro from a file
|
||||
or from a Q-register which failed miserably.
|
||||
|
||||
22.Changed ReadEI() <again>. When ReadEI() finds a line containing double
|
||||
<ESC>'s, it returns to DoEI(), which then executes everything up to that
|
||||
point. DoEI() then re-calls ReadEI() to finish reading the EI file. The
|
||||
problem was that if there were any commands *after* the two <ESC>'s on
|
||||
the last line read, they would be lost in the shuffle because ReadEI()
|
||||
would start reading into the beginning of ZBf. The SQU.TEC macro had
|
||||
a line with commands after a double <ESC>.
|
||||
|
||||
23.Fixed ExeO(). ExeO() wasn't completely comparing the desired tag with
|
||||
the tag in the command string. So, if the command string had two tag
|
||||
names which start out the same way, for example:
|
||||
|
||||
!aa!
|
||||
!a!
|
||||
|
||||
"Oa" would goto !aa!.
|
||||
|
||||
24.Changed the way some of the colon-modified commands work. I ran into a
|
||||
situation in SQU where "Y<:A;>" was used. If the yank read in the entire
|
||||
buffer, ExeA() would fail immediately, without clearing the colon-modified
|
||||
bit in CmdMod, thus "passing" CmdMod to ";" converting it to ":;". "n;"
|
||||
breaks if n is zero or positive, "n:;" breaks if n is negative. "Passing"
|
||||
CmdMod to ExeSCl() this way completely altered the sense of the ";" break.
|
||||
|
||||
25.Fixed case flagging in TypBuf() and made it faster by not doing the
|
||||
Is_Lower() and Is_Upper() checking if EuFlag() is set to EU_NONE.
|
||||
|
||||
26.Rewrote ZCpyBl() in ZMSDOS.C to use memmove() and memcpy(). They
|
||||
both use 80x86 string instructions and make things much faster.
|
||||
|
||||
27.PopMac() was clearing the contents of the local Q-register table,
|
||||
but wasn't de-allocating the table itself.
|
||||
|
||||
28.Changed PshMac(), PopMac(), FindQR(), and Init() to use pointers into
|
||||
the MStack[] and MStack[].QRgstr tables instead of doing redundant array
|
||||
references. Changed Reduce() in PUSHEX.C to use pointers into EStack[]
|
||||
for the same reason. Using pointers should be faster?
|
||||
|
||||
29.The digit buffer (DBfBeg) was initialized in TECOC.C as:
|
||||
|
||||
charptr *DBfBeg = " ";
|
||||
|
||||
then digits were poked into this statically allocated string which really
|
||||
isn't kosher. Changed it so DBfBeg is initialized in MemIni() in INIT.C.
|
||||
|
||||
|
||||
06-Dec-1989 version 120
|
||||
|
||||
1. Changed ExeEO() in EXEE.C to make the version number 120.
|
||||
2. Fixed bug in ZDspBf caused by "length" wrapping when unsigned.
|
||||
3. various little fixups.
|
||||
|
||||
|
||||
07-Dec-1989 version 121
|
||||
|
||||
1. Changed ExeEO() in EXEE.C to make the version number 121.
|
||||
2. Made EC clear the edit buffer after writing files. Thanks, Phil.
|
||||
3. Fixed ZFWrite in ZMSDOS.C to handle files > 64k better.
|
||||
|
||||
|
||||
20-Dec-1989 version 122
|
||||
|
||||
1. Changed ExeEO() in EXEE.C to make the version number 122.
|
||||
2. Added TVERSION (version number of TECOC-C) to TECOC.C
|
||||
3. Fixed ZRdLin in ZVMS.C to make EI commands work.
|
||||
4. Removed the ZInit function. It was being called late (after MemIni),
|
||||
and turned out to be unused anyway.
|
||||
|
||||
|
||||
04-Feb-1990 version 123
|
||||
|
||||
1. Changed ExeEO() in EXEE.C to make the version number 123.
|
||||
2. Removed funny handling of lines terminated with <ESC><CR><LF> do let
|
||||
MS-DOS users edit macros without funnyness.
|
||||
3. Regularized the "debugging level" numbers documented with DbgDMs in
|
||||
TECOC.C.
|
||||
4. Fixed looping logic in SrcLop to make "n_text$" commands work.
|
||||
5. Fixed bug in ClTrEx in ZVMS.C so running from batch works.
|
||||
|
||||
|
||||
20-Feb-1990 version 124
|
||||
|
||||
1. Changed TVERSION in TECOC.H to 124.
|
||||
2. Rewrote MakDBf to make it more portable.
|
||||
|
||||
|
||||
2-Mar-1990 version 125
|
||||
|
||||
1. Changed TVERSION in TECOC.H to 125.
|
||||
2. Fixed so HP with an empty buffer doesn't cause an error message.
|
||||
3. Moved the decision about whether to add/remove CR/LF pairs to/from the end
|
||||
of lines when doing file I/O into the system-dependent functions. This
|
||||
was needed to make MD-DOS happy, and is really where this stuff should
|
||||
be anyway.
|
||||
4. Defined GotCtC as "volatile".
|
||||
5. Rewrote ZRdLin in ZVMS.C to do what TECO-11 really does with all the
|
||||
special characters.
|
||||
6. Put a check for an open output file into ExeEC, so the command HKEFEX
|
||||
will work even if there's more pages in the input file.
|
||||
7. Merged WrBufr and ZWrLin into a singl function called ZWrBfr. Deleted
|
||||
WRBUFR.C and updated the build files. This was needed to provide system
|
||||
dependent control over output so MS-DOS I/O could be cleaned up.
|
||||
|
||||
|
||||
22-May-1990 version 126
|
||||
|
||||
1. Changed TVERSION in TECOC.H to 126.
|
||||
2. Removed code that adds a CR/LF to each record read by ReadEI.
|
||||
3. Fixed VMS output code in ZWrBfr broken in version 125.
|
||||
4. Changed TypBuf so it is interruptable by ^C after displaying a line.
|
||||
5. Defined ChkCtC() so that ^C's work better under MS-DOS.
|
||||
6. Changed ZSWild & ZPWild to work better under CHANGE.TEC.
|
||||
7. Folded wildcard filename buffer (WBf) into "normal" filename buffer (FBf)
|
||||
so G* after ENfilespec$ returns "filespec".
|
||||
|
||||
|
||||
1-June-1990 version 127
|
||||
|
||||
1. Changed TVERSION in TECOC.H to 127.
|
||||
2. Modified ZDoCmd() in ZMSDOS.C so you can EGfilename.BAT$.
|
||||
3. Added EBfFul to avoid "?MEM memory overflow" messages when reading large
|
||||
files. Now TECO-C quietly stops reading.
|
||||
4. Reduced number of times ChkCtC() is called to speed display up.
|
||||
5. renamed AAAREADME.TXT to AAREADME.TXT, needed by MS-DOS
|
||||
|
||||
|
||||
8-June-1990 version 128
|
||||
|
||||
1. Changed TVERSION in TECOC.H to 128.
|
||||
2. Fixed loops that initialize IsOpnI, IsEofI and IsOpnO in Memini. Thanks
|
||||
to Chuck Cranor.
|
||||
3. Added ZExit, ZClnUp and ClenUp and replaced ZAbort with TAbort. This
|
||||
modularizes exit handling.
|
||||
4. Applied lots of fixes to zunix.c suggested by Chuck Cranor. These include
|
||||
terminal initialization and use of termcap for terminal sequences.
|
||||
5. Added a type cast to FindQR to prevent a compiler warning.
|
||||
|
||||
|
||||
13-June-1990 version 129
|
||||
|
||||
1. Changed TVERSION in TECOC.H to 129.
|
||||
2. Made n^T display n modulo 256 instead of generating an error when n
|
||||
is out-of-range. Now it matches documentation.
|
||||
3. Worked on file I/O in ZUNIX.C.
|
||||
|
||||
|
||||
20-June-1990 version 130
|
||||
|
||||
1. Changed TVERSION in TECOC.H to 130.
|
||||
2. Applied Tom Almy's MS-DOS fixes to prevent conversions of line feeds
|
||||
written to the terminal to carriage-return/line-feed pairs.
|
||||
3. Applied Tom Almy's fixes to the search code. Now backwards searches
|
||||
work better.
|
||||
4. Applied Tom Almy's fixes so eight-bit characters are better supported.
|
||||
5. Minor fixes to ExeW.
|
||||
6. Replaced ZRdLin in ZMSDOS.C with Tom Almy's superior version.
|
||||
7. EBfFul was a global used only by RdLine, ExeA and RdPage. I made it
|
||||
an argument. Seemed like the right thing to do.
|
||||
8. Changed the type of the length argument to InsStr from LONG to ptrdiff_t.
|
||||
9. Applied Tom Almy's fixes to DoEvEs and ReadCS.
|
||||
10. Fixed up PG.RNO and created a new PG.MEM.
|
||||
11. Removed BYTE identifier from ZPORT.H and did related fixups.
|
||||
12. Started (by no means complete) supporting 8-bit characters throughout
|
||||
the code. In most cases, this means changing things declared "char"
|
||||
to be declared "unsigned char".
|
||||
13. Deleted DSPCHR.C, which wasn't even compiled.
|
||||
|
||||
|
||||
17-July-1990 version 131 (Manfred)
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 131
|
||||
1. In TECOC.C, ChrMsk[], changed 128 RCS_DEL entries Pete added to RCS_DEF.
|
||||
2. In ZMSDOS.C, added #include <fcntl.h> to get O_BINARY #define. In
|
||||
ZTrmnl(), added "setmode(fileno(stdout),O_BINARY)" per Tom Almy.
|
||||
3. In MAKEFILE.TC, added -K (default to unsigned char) to TCC so string
|
||||
literals which are signed char ptr's don't conflict with the unsigned
|
||||
char ptr's now used all over to get eight-bit chars per Tom Almy.
|
||||
Also added tabort.obj to TECOC_OBJS macro. Also added -DTCPP100 macro.
|
||||
4. In ZPORT.H, changed EBFEXP, EBFINIT, IBFEXP, IBFINIT from 64000
|
||||
to 64000L to get rid of TC++'s "Constant is long" warnings.
|
||||
5. In ERR.C, ToErr(), got rid of TC++'s "Conversion may lose significant
|
||||
digits" in Sbuf[DBfPtr-DBfBeg] line by using SLen to hold DBf length;
|
||||
changed bogus compare "> '\126'" to "> '\177'"; also, the final ']'
|
||||
was overwriting last digit in SBuf.
|
||||
6. In RDLINE.C, changed function return type of expand_ibf from an
|
||||
"static" to "static void". Also added prototype.
|
||||
7. In TECOC.H, added prototype for errprt().
|
||||
8. In RDLINE.C, expand_ibf(), added #if DEBUGGING lines so DbgFNm is declared.
|
||||
9. In ZMSDOS.C, ZRdLin(), fixed typo in #if DEBUGGING "FAILURE" section.
|
||||
10. In ZMSDOS.C, ZRaloc(), added test for TC++ v1.00 since the heap layout
|
||||
has changed. In TC v2.0? mimic farrealloc(), in TC++ v1.00 call
|
||||
farrealloc() directly.
|
||||
|
||||

18-July-1990 version 132
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 132
|
||||
1. lots more work to resolve type mismatches, so lint and gcc don't
|
||||
complain so much.
|
||||
2. fixed the ? immediate-mode command.
|
||||
3. used GAPMIN in RdLine to fix wasteful memory use.
|
||||
4. removed superflous parentheses from return statements.
|
||||
5. to test that identifiers defined in ZPORT.H are minimally consistent,
|
||||
added some tests in TECOC.C
|
||||
6. To finish up eightbit handling, added ZSetTT, a function to let TECO set
|
||||
terminal characteristics. Since it's there, added code so the 1:W and
|
||||
2:W commands change screen size. Not video yet, but a little closer.
|
||||
7. Changed ZMkOFN into a macro named ZMKOFN.
|
||||
8. Fixed ZChIn to handle NoWait correctly.
|
||||
9. Fixed handling of 0,32et bit.
|
||||
|
||||
(8-August-1990 Manfred)
|
||||
|
||||
10. In TECOC.C, changed "\n" to "\r\n" in debugging displays since stdout
|
||||
is now in binary mode.
|
||||
11. In INIT.C, in MemIni(), added Tom Almy's suggestion to temporarily
|
||||
allocate a small chunk of memory to be used as a small-allocation
|
||||
memory pool which may help keep memory fragmentation down.
|
||||
12. In ZPORT.H, removed unused UWORD typedef.
|
||||
13. In ZMSDOS.C, in ZVrBos(), changed old style function definition.
|
||||
14. In ZMSDOS.C, propagated MPtrs[] dynamic allocation tracking to ZRaloc(),
|
||||
added TC++'s new heapcheck() routines to check the heap on every alloc,
|
||||
realloc, and free. We *are* DEBUGGING and don't care about speed
|
||||
penalties, right?
|
||||
15. In ERR.C, the one-line error messages for ERR_PES and ERR_PDO were
|
||||
switched (Argh!).
|
||||
16. In ZPORT.H, expanded EXS_SIZE, LPS_SIZE, MCS_SIZE, and QRS_SIZE so
|
||||
SQU.TEC has some breathing room. Should these expand themselves?
|
||||
17. Some of the .TEC and .TES files supplied with TECO-C were padded with
|
||||
NUL's and some lines ending with ESC had an extra CR.
|
||||
18. In ZMSDOS.C, ZDspCH() called write(). should call fwrite() or we're
|
||||
mixing calls to write/fwrite on stdout which is bad. also, the code
|
||||
which directly set stdout->flags'_F_BIN bit after setmode(stdout) in
|
||||
ZTrmnl() somehow was lost between Pete's version and mine (?)
|
||||
19. In ZMSDOS.C, in ZRdLin(), iBuf was cast as "char far *", should have
|
||||
been cast simply as a "char *" otherwise compiling w/small data model
|
||||
doesn't work.
|
||||
20. In CHANGE.TES, changed some ^U constructs so it's now SQUishable.
|
||||
21. In ZMSDOS.C, added ff_path[] to save ENfilespec$ wildcard lookup
|
||||
filename since we can't be sure FBf will still contain the wildcard
|
||||
lookup filename between ENfilespec$ and EN$.
|
||||
22. Changed CLPARS.TES so when you MUNG there's no leftover trash in
|
||||
q-register 0. (Pete)
|
||||
|
||||
|
||||
19-August-1990 version 133 (Manfred)
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 133
|
||||
1. In EXEO.C, added support for computed gotos (nOtag0,tag1...$)
|
||||
2. In INIT.C, in MemIni(), the digit buffer was being overrun on -1== since
|
||||
the calculation to allocate the digit buffer either: a) didn't take into
|
||||
account that 32-bits-per-long/3-bits-per-octal-digit doesn't divide evenly
|
||||
(loses 2 bits), or b) didn't take into account that ExeEqu() might append
|
||||
<CR><LF> to the digit buffer for =, ==, or === display purposes.
|
||||
3. In ZMSDOS.C, fixed MPtrs[] tracking in ZRaloc, didn't work correctly
|
||||
when farrealloc() eventually returns NULL.
|
||||
4. In TECOC.C, added Turbo C's heapcheck() routine to check_consistency().
|
||||
5. In RDLINE.C, in RdLine(), after expand_ibf(), was calling ZRdLin() even
|
||||
if EBfFul was set TRUE. I don't think it should, even though we might be
|
||||
able to read a line less than IBFMIN bytes long.
|
||||
|
||||
|
||||
9-September-1990 version 134 (Pete)
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 134
|
||||
1. Changed the way I handle conditional inclusion of debugging code.
|
||||
Borrowing from the way the ANSI assert macro works, all the debugging
|
||||
functions are now macros, which don't produce any code if DEBUGGING
|
||||
is FALSE.
|
||||
2. Added TECOC.OPT so the VAX linker puts literal text strings into a
|
||||
non-writeable PSECT.
|
||||
3. Fixed ExeBSl so it will read a numeric string from the edit buffer even
|
||||
if it's preceded by a minus-sign or plus-sign, and fixed TSTBSL.TEC
|
||||
so it tests for these cases.
|
||||
|
||||
|
||||
18-October-1990 version 135 (Pete)
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 135.
|
||||
1. Updated PG.RNH/PG.MEM again.
|
||||
2. Fixed define of DBGFEX in TECOC.H so DEBUGGING works again.
|
||||
3. Fixed FindQR and ExeM to make TECO-C handle :M commands correctly.
|
||||
|
||||
|
||||
21-November-1990 version 136
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 136.
|
||||
1. Fixed DBGFEX syntax bug on line 1118 of ZMSDOS.C
|
||||
2. Removed extra close parenthesis in EXEW.C
|
||||
3. Fixed BLDSTR.C to allow searching for nulls. Thanks to Tom Almy.
|
||||
4. Fixed ExeFGt to work correctly. Bug found by Richard Graham.
|
||||
5. Added missing enblosing braces in InsStr. Thanks to Mark Henderson.
|
||||
6. Added Mark Henderson's additional code to BldStr to provide ^EQ* (file
|
||||
spec buffer) and ^EQ_ (search string buffer) support. Then broke BldStr
|
||||
into functions for readability.
|
||||
7. Inserted Mark Henderson's time and date code into ZUNIX.C. Testing with
|
||||
DATE.TEC revealed a slight bug, fixed.
|
||||
8. Added ZAMIGA.C and some mods to ZPORT.H from Ben Mesander to support
|
||||
TECO-C under Amiga-DOS. Thanks Ben!
|
||||
9. Fixed ExeEQ so it preserves the state of FFPage when reading files.
|
||||
Thanks to Mark Henderson.
|
||||
10. Added ZBell function to make the bell sound better under MS-DOS.
|
||||
Thanks to Steve Freyder.
|
||||
11. Added Mark Henderson's code (he got glob.c from Berkeley stuff)
|
||||
to do wild-carding of file names. Reorganized it some. Thanks, Mark.
|
||||
12. Added Mark's code to name backup files sort of like VMS. Not sure I
|
||||
like this yet, because I haven't tried it. ED bit 4 controls it, like
|
||||
so (from Mark:)
|
||||
ED&4 now specifies the mechanism for backup files
|
||||
if ED&4 is set then we use the foo foo.bak mechanism (as originally)
|
||||
if ED&4 is clear the first backup file will be named foo;1, the
|
||||
second foo;2, ...&c. Sort of VMS like, but the most recent
|
||||
version will be known by the name foo.
|
||||
13. Mark added TECFILES environment variable.
|
||||
If for ei commands and TECO.INI the file is not found in the
|
||||
current directory the directory $(TECFILES) will be searched.
|
||||
I've been keeping my teco startup files in ~/.teco
|
||||
|
||||
|
||||
26-December-1990 version 137
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 137.
|
||||
1. Minor fixups to get ZUNIX.C to compile.
|
||||
2. Moved the line that resets FFPage to zero. It was in RdPage, now it's
|
||||
in RdLine so a 1:a command now correctly resets flag. Thanks to Richard
|
||||
Graham for reporting this one.
|
||||
3. Modified ExeCtE so you can now set the flag as well as get its value,
|
||||
like in TECO-11 and TECO-32.
|
||||
4. Fixed ExeBSl so it sets RefLen when it converts a digit string in the
|
||||
edit buffer into a binary value. Thanks to Mark Henderson.
|
||||
5. Merged in new Amiga support files from Ben Mesander. There's a new
|
||||
ZAMIGA.C, which now has time and date support. Ben supplied files
|
||||
MAKEFILE.AMI and TECOC.LNK for building on the Amiga.
|
||||
|
||||
|
||||
29-December-1990 version 138
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 138.
|
||||
1. Rewrote the TSTO.TEC macro, which pointed out a bug in TECO-32!
|
||||
2. Added "smallcode smalldata" to LFLAGS vlue in MAKEFILE.AMI to make TECO-C
|
||||
smaller (for faster startup) under AmigaDOS. Thanks to Ben Mesander.
|
||||
3. Moved OpnInp and OpnOut into ExeE because only ExeE functions call them.
|
||||
4. Changed ZOpInp function in ZVMS to do the right thing with the default
|
||||
macro library directory. ZAMIGA.C, ZUNIX.C and ZMSDOS.C need to be
|
||||
changed.
|
||||
|
||||
|
||||
10-January-1991 version 139
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 139.
|
||||
1. Fixed ZUNIX.C so it handles default EI file names correctly. Still needs
|
||||
ZClnEG to be implemented.
|
||||
2. Applied Mark Henderson's patch to ZChIn to fix Control-C handling.
|
||||
3. Applied Mark Henderson's patch to ExeEQ to fix EBFEnd pointer screw-up
|
||||
when reading a large file with EQ. Thanks again, Mark!
|
||||
4. Applied Ben Masander's patch to ZAMIGA.C to correctly call isatty.
|
||||
5. Implemented "SYM" part of :EG command for VAX/VMS, so TECO-C can set DCL
|
||||
symbols like DEC's TECO.
|
||||
|
||||
|
||||
20-January-1991 version 140
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 140.
|
||||
1. Reworked ExeEG and ZClnEG to make it work under Unix and to do the
|
||||
system dependent stuff in the right places.
|
||||
2. Modified GENCLP to make it create clpars as "unsigned char" instead of
|
||||
"signed char" to remove a gcc warning. Made GENCLP compile/link/run under
|
||||
SunOS and modified MAKEFILE.SUN to include processing of GENCLP.
|
||||
3. Changed GENCLP.C to define clpars as "const" for ANSI compilers.
|
||||
4. Received another ZAMIGA.C from Ben Mesander. He is now using RCS to
|
||||
control revisions, so there'll be version numbers for ZAMIGA.C from now
|
||||
on. This is version 1.4.
|
||||
5. Implemented Mark Henderson's suggestion to make the size of error
|
||||
message buffers a #define'd identifier. I named it ERBFSIZ.
|
||||
6. Merged in Mark Henderson's video support. This involved a LOT of
|
||||
changes, including:
|
||||
a. Merged MOVE.C into ZUNIX.C
|
||||
b. changed VOID to VVOID to avoid clashing with CURSES.H
|
||||
c. lots of added code with "#if CURSES" control
|
||||
d. created VIDEO.TXT
|
||||
e. created an EZ mode control flag for Mark's bits.
|
||||
f. added exetil.c
|
||||
|
||||
|
||||
23-February-1991 version 141
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 141.
|
||||
1. Some slight changes to make lint happy.
|
||||
2. From Manfred: added DBGFEN calls to DoCtVW and DoCtE in BldStr, fixed
|
||||
DbgFNm in ExeF, removed extra "#include <dos.h>" from ZMSDOS.C, added
|
||||
"fclose(fp)" to init_code_checksums in ZMSDOS.C, and some other minor
|
||||
fixups in ZMSDOS.C. Changed MAKEFILE.TC to avoid "Abnormal Program
|
||||
Termination".
|
||||
3. Added check of terminal width & height to ExeW for 0,1:w error.
|
||||
4. Added Mark Henderson's fix to let ZUNIX.C compile under SunOS 4.0.
|
||||
|
||||
|
||||
15-March-1991 version 142
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 142.
|
||||
1. Added Ben's fixes to slight build problems on AmigaDOS.
|
||||
2. Fixed makefile.sun to make it handle SunOS 4.1 as well as 4.0. Still
|
||||
needs hand-editing to the makefile before running it. Defaults to 4.1.
|
||||
3. Added some fixes to ZUNIX.C to reduce gcc warnings.
|
||||
4. Repaired makefile.sun, which was broken.
|
||||
5. Fixed EXEFTIL.C and EXEF.C so they compile when DEBUGGING is defined.
|
||||
|
||||
|
||||
20-April-1991 version 143
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 143.
|
||||
1. Changed CLPARS.TEC to parse Unix command lines with "-" for options
|
||||
instead of "/".
|
||||
2. Under Unix, changed ZClnEg to implement last-file-edited memory using
|
||||
files in /tmp instead of gawdawful TECF00.TMP files in the current
|
||||
directory.
|
||||
3. Slight include file #ifdef changes to let it compile under SunOS 4.1.1.
|
||||
4. Changed makefile.sun to not use a library. It's much faster this way.
|
||||
5. Added case for tilde command to SkpCmd.c.
|
||||
6. Those C files that directly include curses.h needed to have the
|
||||
#include moved above zport.h.
|
||||
7. Fixed ExeW so if we're not compiled with video, it returns nothing
|
||||
instead of FAILURE, like TECO32. Returning FAILURE causes the current
|
||||
macro to fail, and the current macro might be CLPARS!
|
||||
8. Fixed ZUNIX.C so ET_UNIXNL is correctly defined.
|
||||
9. Added Jerry Leichter's fixes to port to Ultrix, including makefile.ulx.
|
||||
10. Fixed bug in ZUNIX.C where ZDspCh was being called with a string instead
|
||||
of a character. Thanks Jerry!
|
||||
|
||||
|
||||
2-June-1991 version 144
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 144.
|
||||
1. For the ^P command (for debugging, must compile with DEBUGGING set)
|
||||
to work, each function that starts with a call to DBGFEN needs to have
|
||||
a call to DBGFEX before every exit point, or the pretty nesting gets
|
||||
screwed up. Added some DBGFEX calls to BldStr and ZOClos (in ZUNIX.C)
|
||||
to fix the display when 4,0 is used.
|
||||
2. Fixed DoFlag, ExeCtR, ExeCtT, ExeW and ExeBSl so they check the expression
|
||||
stack correctly. They can now be used in expressions without problems.
|
||||
Thanks to Mark Henderson and Jerry Leichter for reporting this.
|
||||
3. Moved the check for "negative argument to comma" from ExeCom to GetAra,
|
||||
where it belongs. This allows -1,5:w commands to work. Thanks to Jerry
|
||||
Leichter.
|
||||
4. Instead of "unterminated command", GetNmA now returns "ill-formed
|
||||
expression", an new error message, when the stack is bogus.
|
||||
|
||||
|
||||
5-June-1991 version 145
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 145.
|
||||
1. Modified PshMac to test set NumArg correctly, so a command like
|
||||
^UA1$2+MA=$$ will work.
|
||||
2. The "#else" on line 122 of ZUNIX.C should be a "#endif".
|
||||
|
||||
|
||||
5-June-1991 to 18-June-1993 version 146
|
||||
|
||||
0. Changed TVERSION in TECOC.H to 146.
|
||||
1. Removed the ~ and F~ commands (the EXETIL.C file and the ExeFTi function)
|
||||
They were temporary commands used by Mark Henderson.
|
||||
3. Added makefile.cct, fixed various minor nits suggested by CodeCenter.
|
||||
4. Fixed error in the way the EI command reads files. If the file being
|
||||
read was too large for the buffer, memory was getting stomped. Thanks
|
||||
to Mark Henderson for reporting the bug in detail and suggesting a fix.

This file contains informal notes about TECO-C. It includes bugs
|
||||
and ideas for improvements.
|
||||
[Unfortunately, it isn't as up to date as possible, some problems
|
||||
in here are fixed, some aren't strictly "problems"...Manfred]
|
||||
. Mark made ~ and F~ commands which aren't documented.
|
||||
. Mark aded Curses support, which works for split screen scrolling but
|
||||
doesn't support vtedit. It also needs to completely enter or leave
|
||||
split screen mode when the 7:W command is executed, because I/O is
|
||||
lousy to the screen if curses is active, even when all it should do
|
||||
is simple output to the screen.
|
||||
. n,m:w commands should return a value, but don't
|
||||
. Steve Freyder's bug: <-^N-1;a> on a large file loops infinitely under
|
||||
MS-DOS and/or Unix?
|
||||
. if you set eightbit (4096,0et) with TECOC and exit, it stays set. If you
|
||||
do it with TECO32, it doesn't. Why? Changing the screen height/width
|
||||
works as expected. (VMS)
|
||||
. do a 0,1:w to TECO32, it just returns. Do it to TECOC, it dies with
|
||||
bad parameter value. TECOC should be the same.
|
||||
. I do a getdvi on the output channel and then do a sensemode in
|
||||
open_output_terminal. They're redundant. The sensemode should be it.
|
||||
. EW causes a backup file to be created.
|
||||
Problems reported by Richard Graham:
|
||||
. EI$ doesn't seem to work. EIfilename$ does. (unsure about this)
|
||||
. :]p= returns -1 10 times, then 0 if executed when TECO first starts
|
||||
up on a PC.
|
||||
. Try ":stext$ .ue :s$" and get ISA error, and then (on PC) the ?
|
||||
command doesn't work. Generalized problem: TECO-C doesn't
|
||||
"overwrite" a numeric value that's on the stack with a new one.
|
||||
. How to search for a control-E? ED flag # 1, ^Eq and ^Eu don't
|
||||
seem to let Richard do it. He says TECO-11 will take FS^E$^E$.
|
||||
Problems running under Unix:
|
||||
. ^C doesn't work.
|
||||
. look at "man 3 time" and "man localtime" to implement date/time
|
||||
. Is there a way to sensibly set ET_EIGHTBIT under Unix?
|
||||
. ZUNIX.C's ZChIn doesn't handle the NoWait argument
|
||||
Problems running on PC:
|
||||
1. editing .EXE files doesn't work. should it?
|
||||
2. ZChIn doesn't handle PC-extended characters from the keyboard
|
||||
3. After the work to make ^C's work better, doing a ^C in the
|
||||
middle of a macro like detab.tec now works; but, ".=" displays
|
||||
0. shouldn't . be in the middle of the file wherever the
|
||||
^C happened?
|
||||
There's a test case in TSTQR.TEC that causes TECO-11 to give the
|
||||
UTC error. TECOC does too, but from then on it's screwed up. Why?
|
||||
To support eight-bit characters, there are several places where casts
|
||||
to "unsigned char" are used. The better solution is to go through the
|
||||
code and declare everything to be unsigned char, then delete the
|
||||
casts. Some of the casts are in CHMACS.H.
|
||||
If you search for a string using a match control construct and the
|
||||
search fails, the "?SRH Search failure "xxx"" error message shows the
|
||||
match control construct with a <> surrounding it. TECO-11/32 does
|
||||
not.
|
||||
BldStr is used by commands other than search commands, yet it reports
|
||||
the "illegal search string" error sometimes. It looks like the error
|
||||
messages from TECO-11/32 aren't really correct. Need an error message
|
||||
like "illegal string build construct" or something.
|
||||
The error message "illegal ^E command in search string" would be
|
||||
better if it were "illegal ^E construct in search string"
|
||||
In ERR.C, the routines ErrMsg, ErrStr and ErrPSt all share code. Fix
|
||||
it. make verbose messages for system errors. flesh out error
|
||||
handling in z files Make a test case that checks the cases:
|
||||
1. call to ErrMsg
|
||||
2. call to ErrChr
|
||||
3. call to ErrStr
|
||||
4. call to ErrPSt
|
||||
5. call to ZVrbos on VAX and non-VAX machines
|
||||
re-indent the code (automatically) to use 4-space indenting. This
|
||||
will solve the problem that some lines are now too long. use clean
|
||||
indenting scheme
|
||||
A command like n+^T$$ won't get parsed right. Is this a general
|
||||
problem?
|
||||
merge zfrsrc and baksrc
|
||||
convert pushex to pshnbr and pshopr
|
||||
terminal modes aren't right on Sun
|
||||
use standard Isdigit, etc. macros/functions?
|
||||
The non-VMS ZPrscl's concatenate argv's and spaces to re-construct the
|
||||
command line. There are better ways that are operating-system
|
||||
dependent.
|
||||
The construct: <0a"ad>' is not well-formed in TECOC, but it is in
|
||||
TECO-11/32 The loop exits when the "end loop" command is skipped. In
|
||||
TECOC, this means the loop nesting control variable isn't decremented,
|
||||
so we "think" we're still in a loop even though we're not. This isn't
|
||||
a problem in TECO-11/32. A more common programming construct is:
|
||||
<0a"ad|1;'> which works without problems in TECOC.
|
||||
The @-modified form of the ! "command" is supported in TECO-11/32, not
|
||||
in TECOC.
|
||||
In BOTH tecos, output of a long string to SYS$OUTPUT doesn't work if
|
||||
the string is long enough. TECOC gets a signal, TECO-11/32 gets a
|
||||
"OPCODE reserved to Digital" error. To fix, must make the "terminal
|
||||
output buffer" dynamic.
|
||||
All system calls must correctly handle being interrupted by control-C.
|
||||
Page 228 of "Unix Programmer's Manual, Volume 1" talks about this a
|
||||
little. Each system call should check for errors, but should not
|
||||
treat control-Cs as an error.
|
||||
If type ^C while it's executing a macro, get "Operation completed
|
||||
under control-C" and a dollar sign!
|
||||
If you type a control-C while help is being displayed, you get two
|
||||
prompts
|
||||
Control-C works fine at command splits. Checks need to be inserted
|
||||
everywhere commands do loops on command arguments. For instance, 23p
|
||||
needs a check in the loop that calls SinglP.
|
||||
Does ExeCtT do the right thing when it's read with no wait and the
|
||||
user types control-C?
|
||||
The following weird thing happens (I forget which TECO):
|
||||
1. compile a file/DEBUG/NOOPT in one terminal session
|
||||
2. open the file with TECO in another session
|
||||
3. debug the application in the first session. Can't find file.
|
||||
4. do ^Z^Z to leave TECO in the second session
|
||||
5. file is deleted!!!
|
||||
The ^EUq string build construct behaves differently than the
|
||||
TECO-11/32 algorithm for a special case: if the character in the
|
||||
q-register is a ^E. The command "5uas^EUA$" will search for ^E in
|
||||
TECO-11/32 and will fail in TECO-C.
|
||||
ZFrSrc exists only because I was playing with SCANC on a VAX. Delete
|
||||
the VAX-specific code and then merge what's left with BakSrc, using
|
||||
SIncrm in the loops. This is much cleaner.
|
||||
Local q-registers need to be tested further.
|
||||
CBf, SBf, TBf, ZBf do not expand?
|
||||
Finish creation of TSTPW.TEC, a test case that demonstrates that
|
||||
ZWRITE mimics TECO-11/32 for all cases of the edit buffer/gap and all
|
||||
cases of line termination: FF, VT, CR/LF, $/CR/LF, and GapBeg and
|
||||
GapEnd.
|
||||
Open SOFDEV.RNO for reading, do _glossary$v$$ and see junk. Also, do
|
||||
rt -r notes.rno and then y$$y$$ and see an extra blank line at the
|
||||
bottom of the buffer.
|
||||
Use TRNLNM instead of TRNLOG in ZINIT and ZEXEEI. Make a
|
||||
general-purpose logical name translation procedure to be used by both?
|
||||
File COMMANDS.TXT has several "not implemented" lines that aren't
|
||||
right
|
||||
Add help text for E%q and EQq to hlp file.
|
||||
In TECO-11/32, the EG command uses the BldStr-like routine to build
|
||||
its string. Teco-c should call BldStr from ZExeEG.
|
||||
The macro system needs to be carefully checked.
|
||||
If do 8192ET, then a null command string with just two escapes won't
|
||||
"work". Need to hit three, and then get an error.
|
||||
Scan Appendix C of TECO-11/32 manual for goodies.
|
||||
In ZExeEI:
|
||||
1. status != RMS$_NORMAL in ZRedEI does not error
|
||||
gracefully.
|
||||
2. If find $$ in the middle of the read buffer, can't
|
||||
continue after executing the string.
|
||||
3. EI buffer won't expand.
|
||||
4. File closure on error on ^C ?
|
||||
ExeCSt was changed to do CBfPtr < CStEnd instead of CBfPtr <= CStEnd.
|
||||
Track and check.
|
||||
Why clear q-register stack in MemIni if it's been statically
|
||||
initialized in TECOC?
|
||||
Page 5 of TECO.LST shows ET and ED encodings. Compare/contrast
|
||||
In ExeFGt, if we're not in a loop, should behave as if we're
|
||||
<ESC><ESC>. We're not doing that now. Put in
|
||||
If (MstTop)
|
||||
{
|
||||
CBfPtr = CStEnd;
|
||||
return(SUCCESS);
|
||||
}
|
||||
into the code before the first return(FAILURE).
|
||||
On the VAX, deal with disk quota overflow. Larry Kilgallen described
|
||||
the handling of this: when you get a disk quota exceeded, just issue
|
||||
the identical $PUT call again to exploit overdraft. This doesn't work
|
||||
for creating files.
|
||||
Date and time (^B and ^H) commands work under VAX/VMS. They will work
|
||||
differently under other systems. Make a standard?
|
||||
Say jz10v instead of zj10v and the two TECO's behave differently
|
||||
Normal TECO handles two numbers in a row differently than TECO-C does.
|
||||
TECO-C dies with a debugging message!!!
|
||||
use register variables
|
||||
use declaration of variables within blocks
|
||||
see if type casts are superfluous in places. C already does it?
|
||||
The September 1984 issue of Scientific American has an article by
|
||||
Niklaus Wirth that describes a fast searching algorithm. Use it?
|
||||
The entire ", ', <, >, O system should be checked.
|
||||
CmdMod should be checked.
|
||||
Is MovGap right?
|
||||
The W command is stubbed out now. For debugging, ExeW exists, SkpE
|
||||
skips over EG, EM, EN and EZ as if they were valid commands. A
|
||||
problem with this is that the command to turn on SEEALL mode
|
||||
"-1,3:W^[" returns ERR_NCA error, "negative argument to comma".
|
||||
The code for INCCBP and the other places where ++CBfPtr happens needs
|
||||
the MStTop test to be changed. Now, if a UTC should be reported, it's
|
||||
not. It returns SUCCESS!
|
||||
ExeO needs it's handling of CBfPtr to be fixed. There aren't checks
|
||||
against CStEnd, and the last "--CBfPtr" may be wrong.
|
||||
Shouldn't CBfPtr be renamed CStPtr? It would relate better to CStBeg,
|
||||
CStEnd, etc.
|
||||
help subsystem works on VAX, won't on another machine
|
||||
Get rid of ??? which marks unfinished or questionable stuff. Get rid
|
||||
of calls to ExeNYI.
|
||||
DoEvEs doesn't implement the ES flag exactly like the manual says
|
||||
DoEvEs has a system-dependent structure (UDummy)
|
||||
the free function is an int on the VAX, void on the SAGE
|
||||
Standard input and standard output are not used to communicate with
|
||||
the terminal. UNIX people may expect that they are. This rules out
|
||||
using TECO-C in a pipe-oriented manner.
|
||||
Use DbgDCh instead of ZDspCh in ErrMsg for passed string displaying
|
||||
difference between TypChr, EchoIt, CharOut?
|
||||
COLON sounds like a character identifier. So does ATSIGN.
|
||||
ChrFuncs requires DefChars
|
||||
memory overflow
|
||||
skipping commands is NOT finished.
|
||||
In help, for errors, trace down the possible ways the code can print
|
||||
each error message. Some of them are unobvious. Give an explanation
|
||||
of all the ways an error can be generated to help a user figure out
|
||||
his error.
|
||||
Page 92 of the manual lists two informational messages. The 16 bit of
|
||||
the ET mode control flag suppresses informational messages. These
|
||||
messages are neither generated nor suppressed by TECO-C.
|
||||
Doing an "ERfilename$" puts the expanded filespec in the filespec
|
||||
buffer. Under TECO-11/32, doing a subsequent "ER$" to change I/O
|
||||
streams does not wipe out the filespec buffer. It does in TECO-C.
|
||||
For all the xxxBeg, xxxEnd, xxxPtr things, change all the comments to
|
||||
xxxBeg; /* first char of xxx buffer */
|
||||
xxxEnd; /* last char of xxx buffer */
|
||||
xxxPtr; /* last char of xxx, plus 1 */
|
||||
check the MOBY MUNGER. It mentions lots of bugs in other TECOs. Some
|
||||
of the bugs are esoteric and quite possibly exist in TECO-C
|
||||
nulls are not stripped from input.
|
||||
VAX TPU is able to read a file that is currently locked by another
|
||||
user, which is useful for looking at BATCH log files while a BATCH job
|
||||
is running. TECO-C can't. I looked at the microfiche code to see how
|
||||
TPU does it. It seems to try to open the file, and if it gets
|
||||
RMS$_FLK, then it tries to open the file again after setting the UPI
|
||||
bit in FAB$SHR. This means that it is supposed to do block I/O to the
|
||||
file. I couldn't find the place where actual file reading is done
|
||||
(it's in $fileio, which is in TPU$CAL_MODULE, which I couldn't find.)
|
||||
Does TPU do block I/O (section mapping?)
|
||||
The following commands are not yet implemented in TECO-C
|
||||
W video scope control
|
||||
^Y equivalent to ".+^S,."
|
||||
EL open log file
|
||||
^F return value in console switch register
|
||||
nEC control memory management
|
||||
The following commands are not implemented in TECO-C, and probably
|
||||
never will be, as they require operating system features that cannot
|
||||
be assumed by a portable TECO.
|
||||
EZ zero output tape
|
||||
EM position magnetic tape
|
||||
In addition, most of the commands defined in Appendix C of
|
||||
the manual (Incompatible, Obsolete and System-Specific Commands)
|
||||
are not implemented.
|
||||
The ^R command (set or return radix) supports the 8, 10 and 16
|
||||
radices. TECO-C parses command-line numeric arguments using the
|
||||
current radix. This can make command execution confusing for radix
|
||||
16. Consider the command string "14A=$$", which returns the ascii
|
||||
value of the 14th character after the character pointer. If the radix
|
||||
is 16, the "A" is parsed as part of the number, and the ascii value of
|
||||
a completely different character will be returned.
|
||||
This is a trade-off. TECO-11/32 always parses command-line arguments
|
||||
using radix 10. This destroys TECO's utility as a calculator for
|
||||
hexadecimal. I believe access to a base 16 calculator is more
|
||||
important than possible user confusion. Thus, be careful if you want
|
||||
to change TECO's radix. Remember to change it back. Also note that
|
||||
if you use TECO-C as a hexadecimal calculator, you must precede
|
||||
hexadecimal numbers which start with one of the letters A-F with a 0
|
||||
in order to make TECO-C parse the number correctly.
|
||||
You won't get "%Superseding file" messages.
|
||||
Differences between TECO-C and TECO-11 or TECO32 under VMS:
|
||||
. video only under Unix, commands somewhat different, see VIDEO.TXT
|
||||
. Command line syntax different under Unix.
|
||||
. EO returns 100+
|
||||
. 2048 bit of ET flag reverses meaning of DELETE and BACKSPACE keys
|
||||
. -1EJ command returns additional operating system types
|
||||
. 0:W returns additional terminal types
|
||||
. s^n$ gives "invalid search argument", TECO-11/32 does nothing
|
||||
. on ^Z^Z^Z, third ^Z is echoed
|
||||
. default directory is TECO$MACROS for EI command
|
||||
. TECO-C won't allow HP or HPW when edit buffer is empty
|
||||
. TECO-C supports q-register I/O commands E% and EQ, TECO-11
|
||||
doesn't
|
||||
. TECO-C supports ^EQ* and ^EQ_ as string build contructs, TECO-11
|
||||
doesn't
|
||||
. TECO-C does case sensitivity correctly, not with bit checking,
|
||||
so TECO-C does not consider "`","{","|","}" and "~" to be
|
||||
equivalent to "@","[","\","]" and "^", respectively.
|
||||
. The -P, -Y, and -N commands, which are implemented in TECO-11
|
||||
version 39, are not yet implemented in TECO-C.
|
||||
. TECO-11 supports switches on file name arguments to commands like
|
||||
ER, EB, etc. TECO-C does not.
|
||||
. TECO-11/32 supports files with nonstandard record formats (like
|
||||
FORTRAN carriage control). TECO-C does not.
|
||||
. TECO-11/32 does funny stuff with lines ending in <ESC><CR><LF>.
|
||||
TECO-C doesn't (it can't under MS-DOS, which uses <CR><LF> as
|
||||
line terminators in files.)
|
||||
. Escape-sequence handling not in TECOC yet.
|
||||
. <DELIM> can be anything in TECO-11/32, not in TECOC
|
||||
. :EGcmd args' is in TECO-11/32
|
||||
. ^T on/off handling in TECO-11/32 is better than in TECOC
|
||||
. values returned by initialization macro are used by TECO-11/32
|
||||
. ^E can be set by the user in TECO-11/32
|
||||
. :^T command exists in TECO-11/32
|
||||
. nOtag0,tag1,tag2$ with an "n" that's out-of-range is supposed to
|
||||
. cause no branch at all. Under TECO-32, a negative "n" causes a
|
||||
branch to tag0. TECO-C correctly does no branch.

Notes from Blake McBride (blake@mcbride.name)
|
||||
Video support under Linux & Mac OS/X has been restored. Getting it to
|
||||
work under Windows would probably be easy (given ncurses support).
|
||||
See the makefile's for instructions on enabling or disabling video
|
||||
support.
|
||||
When a file is being edited, you can execute: 5,7:w$$ to enter video
|
||||
mode (the $ is the escape key). The "5" means 5 scroll lines at the
|
||||
bottom of the screen. The remaining screen space is for the video
|
||||
display.
|
||||
Video mode can be exited with: 0,7:w$$
|
||||
As shown below, you can also startup in video mode using:
|
||||
teco -scroll:5 myfile.txt
|
||||

Command line
|

------- ----
|
||||
-NOPAGE
|
||||
Don't separate input into pages. Instead, treat form feeds
|
||||
as normal characters.
|
||||
+nnn
|
||||
where nnn is any number of digits. Go to line number nnn and
|
||||
set NOPAGE. Note this uses the UNIX end of line convention
|
||||
for use with cc output &c. The non-unix line termination will
|
||||
still be used for nL and other intrinsic TECO commands, this just
|
||||
controls the starting line AT INVOCATION.
|
||||
-SCROLL:nnn
|
||||
do nnn,7:w
|
||||
-SCROLL:nnn:SEEALL
|

seeall is more unix style then you might expect

5:w Hold mode is not properly implemented. I don't like it anyway.
|
||||
7:W Number of lines in command window. The size of the scope window
|
||||
will be (Rows - 7:W (- 1 if ET&256))
|
||||
8:w Attribute for special characters. This is highly implementation
|
||||
dependent (curses implementation dependent). Under SUN OS 4.1
|
||||
0 - no marking
|
||||
1 - underline
|
||||
2 - reverse
|
||||
4 - blink
|

8 - dim
|
||||
16 - bold
|
||||
128 - ALT_CHARSET
|

currently controls marking of <CR> `
|

END OF PAGE (BTEE/+)
|
||||
9:W Bit 0 - keypad support on
|
||||
Bit 1 - do not do timeout escape sequence detection
|
||||
ET&1 image mode - doesn't really do much with curses version
|
||||
ET&2 use scope for delete and control-U
|
||||
ET&4 accept lowercase input
|
||||
ET&32 read with no wait on control-T (unimplemented - easy though)
|
||||
ET&2048 reverse roles of BS and DEL (good if you use stty erase ^H,
|
||||
in particular the key placement of BS is sometimes much easier
|
||||
to get at then DEL). Should I have it detect the kill character
|
||||
and automatically set this?
|
||||
ET&8192 accept ` as escape (for VT220 terminals)
|
||||
ET&16384 special VT200 mode
|
||||
ET&32768 trap control-C
|
||||
EZ&1 if false VMS style versioning for backup files (multiple backups)
|
||||
if true only one backup level (foo, foo.bak)
|
||||
EZ&8 if TRUE use LARROW (<) for CR, if false use `
|
||||
EZ&16 if set then prefer audio beep else visual flash
|
||||
EZ&32 winline divider for scope
|
||||
EZ&128 if set DO NOT stop read on FF otherwise make pages as usual
|
||||
EZ&256 UNIX NL-convert LF to <CR><LF> on input and invert on output
|
||||
ED&512 controls scope display. If set will use VT100 line drawing
|
||||
characters for CR and LF (in non-scope mode). May degrade
|
||||
performance.
|
||||
EZ&2048 if set use BTEE for end of buffer, else use DIAMOND
|
||||
(desirable for pathological terminal types)
|
||||
EZ&8192 don't show CR in scope - closer to TECO-11, but really
|
||||
not as good in my opinion (Mark Henderson)
