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.
