Here's one way:
#\d represents a digit
#this regex checks to see if every character (besides possibly a trailing
\n) is a digit
if($var =~ /^\d+$/){
do something...
}else{
don't
}

Subject: Variable question
Hi everyone.
I was wondering how you would determine whether a variable is a number or
not. I want to do an if statement such as
if ($variable is a number) {...
Any help is great. Thanx,
Helen
