Correction its not that it's a string (which it is) its that int doesn't like 0 even thought it's an integer by definition.

If you are not 100% sure then you can also do if ($x =~/^\d*$/) for an actual integer i.e. a number in the positive whole set of numbers { 1,2,3....} or negative whole numbers -1,-2,-3.... or 0. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: 04 March 2008 20:42 To: [EMAIL PROTECTED] Cc: beginners@perl.org Subject: RE: variable help Thanks Brown.
