removed the need for p-string routines, so they were removed. Also
removed alloc256/free256 and associated data structures.
In removing calls, found instances in pwd & prefix commands and prompt
handler where current directory name was assumed to be < 256 characters;
recoded to use a flexible buffer size.
Updated and expanded mmdebug.asm routines that perform error checking on
memory management calls. Added macros ~NEW and ~DISPOSE that invoke either
the real or debug routines.
Fixed call to read $TERM variable's length to fix PR#81.
Removed echo of data when setting value of $< in expandvars (expand.asm).
The characters are echoed as they are typed and do not need to be reprinted
on stdout after carriage-return is typed.
Added error checking to the various flavors of prefix (just like cd):
- Verify 2nd parameter is a valid directory before setting.
- Verify 1st parameter < 32 before displaying or setting.
and link. However, it does not work yet and thus still needs work.
The *.asm files have had the following common changes:
- 'keep' lines were eliminated
- the 'mcopy' now takes the macro from the /obj/gno/bin/gsh
directory. This is in anticipation of having the macro
files generated from a single source file; there is a large
amount of duplication. For the moment, the makefile merely
copies the old macro files from the "M" directory to the
/obj/gno/bin/gsh directory.
- start each file with a dummy routine so that the source
code winds up in the *.o rather than the *.root file.
- added the 'setcom 60' directive; there were many source
lines that were otherwise getting truncated.
The makefile is a complete rewrite.
