fixing file names in batch programs (MSDOS)

I’m not really familiar with batch programming -What I need to do
is create a batch file which zips some files in somefolder and gives the
zip today’s date  + pre ( before changes )or + post (after
changes) as its name viz.
The file would be say 06-11-1999pre.zi p. i don’t know the command to use
capture the system date and add the extension pre /
post.

You can't without some program(s), dos batch doesn't have output parsing or file parsing. When I need to do something like that in dos I just use qbasic which comes with dos (and the olddos folder on the windows cd)

The info you gave is kinda spotty so I'll have to give you the general idea. Open Qbasic and in the main window type:

SHELL ("ECHO <your zip program><space>"+date$+"pre")

put "+date$+" (include quotes) when you want the date shown

example:
SHELL ("ECHO c:\pk\pkzip "+date$+"pre.zip c:\zipem\*.*")
then press shift-F5, you should see something like this (as per my example:

c:\pk\pkzip 11-11-1999pre.zip c:\zipem\*.*
Make sure this is the command you want to use. Now just remove the ECHO line (it was there to test it)
As per my example:

SHELL ("c:\pk\pkzip "+date$+"pre.zip c:\zipem\*.*")

Then save this file (alt-f-s), I would suggest saving it as text.

Then what you need to put in your batch file is:
Qbasic program.bas

If you want more help just ask and just give us more info :)
