in thread Setting Conditional Variable Based on Partial Match

Thanks for the response. I actually do use strict and warnings, I just left them out of the code that I pasted here. I'll include everything in my program in the future. The backslash tells perl to recognize the character "as is" and not as a special character, correct?
