Sorry, hit the send button early :) Ignore that mail... -----Original Message----- From: John Edwards Sent: 30 August 2001 16:52 To: 'Rajanikanth Dandamudi'; '[EMAIL PROTECTED]' Subject: RE: Doubt It doesn't matter to Perl if you store alphanumerics or numbers or both in scalar. When you want to perform a numeric function on the scalar, Perl treats the data in it as numeric. When you want to perform an alphanumeric on it, it treats the data as alphanumerics. e.g $data = "one"; $new = "$data + 10"; print $new; You could use a regular expression to check the data. Here is some commented sample code # Initialize the scalar and store the string $data -----Original Message----- From: Rajanikanth Dandamudi [mailto:[EMAIL PROTECTED]] Sent: 30 August 2001 16:35 To: '[EMAIL PROTECTED]' Subject: Doubt Hello, My doubt is "How do you identify whether a perl scalar variable contains a numeric value or alphanumeric string?" . I had gone through the explanation available at the URL http://www.cpan.org/doc/FMTEYEWTK/is_numeric.html , but I didn't understand that explanation. Thanks in advance.
