Using KIX scripting (www.kixtart.org) you can accomplish this all in one script file.

Sure can.  There are several ways to skin that cat, here's one (along with quite a few other NT/2K nuggets):

Another common technique is to create a temporary bat file whose name matches the first word generated by the command in question and whose body extracts a particular parameter from the command line.  You then redirect the output of the desired command to another temporary bat file which you then execute. E.g., for capturing the date:

echo set TODAY=%%5 >the.bat
date <crlf.dat >thing.bat
call thing
del the.bat
del thing.bat

crlf.dat is one of those files you always have around for responding to prompts (just like you also have no.dat and yes.dat).

Note that you can avoid the redirected input by using the /t option on DATE.  In that case, however, the output starts with the three letter day name, so you'd have to create sun.bat, mon.bat, etc., and the date would be in %2.

Yes, those should all work under 2k.
