Batch File Variables Troubles

Comment:
I've got a batch file in which I'm having to manipulate a few variables concerning dates. As the program executes, it parses the date into individiual variables such as month number (i.e. 09 for September, 10 for October, etc.). I need to know how to be able to subtract one month from that variable but still have it be two digits (i.e. 10 minus 1 be "09" rather than "9"). Currently, the leading zero on months 01-09 is lost when I make that subtraction.

I assume you are running your batch under Windows NT/2K/XP (an NT-kernel based system) as you stated about string parsing and arithmetic, operations not usually performed under Windows 9X/ME.
If so, after subtraction you have to test
If "%Month:~1,1%"=="" Set Month=0%Month%
and you get the vanished 0.
This works only under the previously reported operating systems. I hope this helps

Obviously in my previous post substitute Month with your variable name!
