Home: Perl Programming Help: Beginner: \d*

emelin stranger Feb 22, 2001, 4:25 AM Post #1 of 2 (1106 views) \d* Can't Post Doesn't "\d*" mean "any number, at least 0 times"? I want the user to enter something like P651... my code lets them enter PJJJ (i.e. anything, as long as it has a p or P in it)... How do I just let them enter PXXX, X being a number? if ($FORM::part =~ /P\d*/i){ continue(); } thankful for help, emelin

Right at the beginning of the string. I can see 0 digits there, and that's what I asked to match. Perhaps you meant \d+. Or, more specifically, \d{3}.
