Re^2: Pattern matching exlusion

Hi Loops, Thank you for your help. Tell me if I am wrong concerning the interpretation of your expression: qr(10-KQ A-Z0-9*(?!/))i; 1. You are saying find a string (QR) 2. which begins with 10-K or 10-Q KQ 3. followed by any letter from A-Z (A-Z] 4. followed by any number 0-9 [0-9} 5. excluding any string which terminates with slash *(?!/))i Is that right? If so, how would the expression change if I were looking for upper case letters only? Your insight is invaluable, and I am grateful! Rick

The `[A-Z0-9]` part of the expression matches any letter or any number. And it's followed by an asterisk "*", which means zero or more instances. So "1B3" and "K4R" both match at that point in the pattern. To use upper case only, remove the trailing "i" from the initial $formget assignment.	[reply] [d/l]
