Price (linux-guru@gcfl.net)) ~~~~~~~~~~~~~~~~~~~~~~~~ COMMAND.C/COMMAND.H: o Now sets COMSPEC environment variable o misc clean up and optimization o added date, time and type commands o changed to using spawnl instead of exec. exec does not copy the environment to the child process!

Price (linux-guru@gcfl.net)) ~~~~~~~~~~~~~~~~~~~~~~~~ COMMAND.C o fixed call to spawnl so that it would pass command line arguments correctly. 07/12/98 version 0.74c (Rob Lake rlake@cs.mun.ca) ~~~~~~~~~~~~~~~~~~~~~~ Various Files: o removed redundant use of error message defines and moved error printing calls to ERROR.C to reduced program size. o created MISC.C o created ERR_HAND.C/H o created ERROR.C 07/13/98 version 0.74d (Rob Lake rlake@cs.mun.ca) ~~~~~~~~~~~~~~~~~~~~~~ INTERNAL.C o removed most of the commands and placed them in there own file -- del, ren, set and ver o created DEL.C, REN.C SET.C and VER.C o fixed bug that caused del not to delete files with no attributes o the critical error handler count number of times called, autofails at 5 calls 16 Jul 1998 (Hans B Pufal ) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ batch.c A new version, implements CALL, ECHO, GOT, IF, PAUSE, SHIFT and BEEP. There is a stub for FOR but that's all. cmdtable.c New file to keep the internal command table. I plan on getting rid of the table real soon now and replacing it with a dynamic mechanism. command.c A new (improved ;) version. Conforms closely to MS-DOS specs. Cleaned up (and fixed) the redirection handler. command.h Version D with changes. Look for the HBP tag. redir.c Modified file, now supports append redirects. 16 Jul 1998 (Rob Lake rlake@cs.mun.ca) ~~~~~~~~~~~~~~~~~~~~~~ Added TRUENAME command. 19 Jul 1998 (Hans B Pufal) ) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ o Preserve state of echo flag across batch calls. o Implementation of FOR command 20 Jul 1998 (John P Price ) ~~~~~~~~~~~~~~~~~~~~~~ o Fixed bug in DATE.C. o Fixed bug in LH.ASM. o Separated commands into individual files. 28 Jul 1998 (John P Price ) ~~~~~~~~~~~~~~~~~~~~~~ o Added CLS command. o Put ifdef's around all commands and added include file config.h Now you can define exact what commands you want to include in command.com. o Also added ifdefs for optional features: aliases, command history and filename completion. o Added display of available internal commands and options at startup. 29 Jul 1998 (Rob Lake rlake@cs.mun.ca) ~~~~~~~~~~~~~~~~~~~~~~ o changed date.c and time.c, and wrote datefunc.c and timefunc.c to implement _dos_getdate, _dos_setdate, _dos_gettime and _dos_settime.

Before command would to execute any file with any extension. (opps!) 30-Jul-1998 (John P Price ) ~~~~~~~~~~~~~~~~~~~~~~ o Fixed bug where if you typed something, then hit HOME, then tried to type something else in insert mode, it locked up. o Changed default insert mode to on. There should be a way to change this. Maybe options to doskey command. o Added VERIFY command 02-Aug-1998 (Hans B Pufal) ) ~~~~~~~~~~~~~~~~~~~~~~ o batch.c: Fixed bug in ECHO flag restoration at exit from batch file o command.c: Fixed return value when called with /C option o Terminate label on first space character, use only first 8 chars of label string 04-Aug-1998 (Hans B Pufal) ) ~~~~~~~~~~~~~~~~~~~~~~ o call.c: added lines to initialize for pointers.
