FINDQR.C:
|
||
|
|
|
||
|
|
Cast is needed to get it to compile under Borland C.
|
||
|
|
|
||
|
|
CLPARS.TES:
|
||
|
|
|
||
|
|
If no EGMEM or if EGMEM and filename starts with a $, then CLPARS
|
||
|
|
gets totally hosed. Major hacking was needed to fix.
|
||
|
|
|
||
|
|
ZMSDOS.C, EXEE.C TECOC.H:
|
||
|
|
|
||
|
|
Backup file is created for EW and other occasions. It should only be
|
||
|
|
created with the EB command (or TECOC TECO on the command line).
|
||
|
|
|
||
|
|
Added BOOLEAN Backup argument to ZMSDOS:ZOpOut. Only make backup if
|
||
|
|
Backup==TRUE. Argument is passed through in EXEE:OpnOut. In
|
||
|
|
EXEE:ExeEB, value passed is TRUE. In EXEE:ExeEW and EXEE:ExeEPr the
|
||
|
|
value passed is False. When file is closed in ZMSDOS:ZOClos then if
|
||
|
|
no backup was wanted we won't create one.
|
||
|
|
|
||
|
|
EXEM.C:
|
||
|
|
|
||
|
|
Colon modified macros pass the colon into the internal command. This
|
||
|
|
prevented the tstqr.tec test file from working.
|
||
|
|
|
||
|
|
The fix is to clear the colon flag if it is set within ExeM().
|
||
|
|
|
||
|
|
EXEM.C:
|
||
|
|
|
||
|
|
Execution of local macros caused new set of local q registers to be
|
||
|
|
generated.
|
||
|
|
|
||
|
|
The fix is to not generate new macro set if macro is local.
|
||
|
|
|
||
|
|
SRCLOP.C:
|
||
|
|
|
||
|
|
n,mFB command did not work unless at gap. Fixed.
|
||
|
|
|
||
|
|
SEARCH.C:
|
||
|
|
|
||
|
|
ES now ignored if in macro or loop
|
||
|
|
|
||
|
|
WCHART.TXT:
|
||
|
|
|
||
|
|
Changed FB and FC as "implemented" Also G* and G_ as implemented.
|
||
|
|
|
||
|
|
ZMSDOS.C: CLPARS.TES:
|
||
|
|
|
||
|
|
Added test for ED_FF flag (in EZ??) to ignore form feeds. Then change
|
||
|
|
clpars.tes so /NOPAGE will set it *before* yanking.
|
||
|
|
|
||
|
|
ZMSDOS.C TECOC.H EXEE.C:
|
||
|
|
|
||
|
|
ZDoCmd used the file name buffer for the command, while ExeEG keeps the
|
||
|
|
command in a local buffer. This prevents EG from working in any version!
|
||
|
|
|
||
|
|
I added arguments to ZDoCmd to pass the command string.
|
||
|
|
|
||
|
|
ZMSDOS.C
|
||
|
|
|
||
|
|
The TEC$LIBRARY environment variable was not being examined for the EI
|
||
|
|
command, unlike at least the UNIX version. This basically made TEC$LIBARY
|
||
|
|
worthless since its only other use was during initializaton for video
|
||
|
|
support, which doesn't exist in MSDOS. So I fixed it.
|
||
|
|
|
||
|
|
|
||
|
|
ZMSDOS.C
|
||
|
|
|
||
|
|
Tecoc has the ugly habit of allowing you to edit a readonly file,
|
||
|
|
only to die on you when you finish. It's easy enough to check that
|
||
|
|
the output file is writable first. The problem is in ZOpOut().
|
||
|
|
|
||
|
|
Because MSDOS TECOC creates the temp file in the current directory,
|
||
|
|
any attempt to EW or EB a file in another drive will cause failure
|
||
|
|
when the rename is attempted. In these cases the file must be copied.
|
||
|
|
ZOClos() is the culprit.
|
||
|
|
|
||
|
|
I added a "fastcopy" function, much like what was done in zunix.c,
|
||
|
|
but quite a bit simpler. The OS/2 version will need this since OS/2
|
||
|
|
prefers copying over renaming to preserve file extended attributes
|
||
|
|
and PM references. The handling in the OS/2 code is slightly
|
||
|
|
different in that the only file that ever gets deleted is the
|
||
|
|
temporary file. When this code is included in the MSDOS version, it
|
||
|
|
takes too much space for compact model, so I don't update the time stamp
|
||
|
|
(that allows it to squeek by).
|
||
|
|
|
||
|
|
Along the same lines, Tecoc will create a backup file in the wrong
|
||
|
|
directory if the file name has an explicit path and has a "." in one
|
||
|
|
of the directory names. ZOClos() is the culprit, again.
|
||
|
|
|
||
|
|
I added the "% Superseding existing file" warning message. Why wasn't
|
||
|
|
it there??
|
||
|
|
|
||
|
|
CLPARS.TES
|
||
|
|
|
||
|
|
After the attempt to do an EB fails, clpars assumed the failure was
|
||
|
|
caused by the input file not being found. Added new code to attempt
|
||
|
|
to open the file via ER - if that succeeds, prints message that file
|
||
|
|
is being opened read-only.
|
||
|
|
|
||
|
|
Added handling for a /NORENAME switch, needed by OS/2. I also added
|
||
|
|
code to remove quotes in a quoted file name string if OS/2. Reason:
|
||
|
|
file names can have embedded spaces, yet quotes are not allowed.
|
||
|
|
|
||
|
|
I couldn't see any reason to strip spaces from the filename saved
|
||
|
|
in "memory" since the name had already been processed. This was causing
|
||
|
|
a problem with the OS/2 version since I stripped the quotes.
|
||
|
|
|
||
|
|
I removed the restriction of the +nnn commandline argument so it
|
||
|
|
would work with MS/DOS and OS/2. Why limit it to UNIX?
|
||
|
|
|
||
|
|
Clpars leaves the macro .T around after completion (remember -- it's
|
||
|
|
not called as a macro if USE_ANSI_CLPARS, which makes it a top level
|
||
|
|
local macro), and also leaves non-zero values in qy, q8, q.l, q4, and
|
||
|
|
possibly q.1. Fixed. However I don't understand the reasoning for
|
||
|
|
*saving* q registers during execution of clpars since there is
|
||
|
|
nothing in them at the start of the macro execution.
