Batch File: Regular Expression

Hi there,

I need to learn more about "Regular Expressions" in a batch file.

Here is an example from "Qlemo".

QUESTION:
Please provide URL of any educational material that will teach me on using "regular expressions" in a batch file, or any quick fix for my knowledge bug.

Thanks for your help,
Rene

   echo,
   echo -------- %C --------
   help %C
   echo,
   pause
)
