Show files matching a given file completion pattern
returns 1 if at least one match, else returns 0
This file bases on FILECOMP.C of FreeCOM v0.81 beta 1.
$Log: fcompl2.c,v $
Revision 1.1 2001/04/12 00:33:53 skaus
chg: new structure
chg: If DEBUG enabled, no available commands are displayed on startup
fix: PTCHSIZE also patches min extra size to force to have this amount
of memory available on start
bugfix: CALL doesn't reset options
add: PTCHSIZE to patch heap size
add: VSPAWN, /SWAP switch, .SWP resource handling
bugfix: COMMAND.COM A:\
bugfix: CALL: if swapOnExec == ERROR, no change of swapOnExec allowed
add: command MEMORY
bugfix: runExtension(): destroys command[-2]
add: clean.bat
add: localized CRITER strings
chg: use LNG files for hard-coded strings (hangForEver(), init.c)
via STRINGS.LIB
add: DEL.C, COPY.C, CBREAK.C: STRINGS-based prompts
add: fixstrs.c: prompts & symbolic keys
add: fixstrs.c: backslash escape sequences
add: version IDs to DEFAULT.LNG and validation to FIXSTRS.C
chg: splitted code apart into LIB\*.c and CMD\*.c
