Re: [UUG/MLUG] perl question fo the day

$bleh in this case will also match 31, 9873, etc... anything with a 3 in
it... (and you also need the //'s or whatever around the regexp) but
basically this does look to be on the right track...

This should work:

...
if (grep(EMAIL:PROTECTED)) {
...

although I'm not sure what this will do with multiline variables (but if
you're just dealing with numbers, and single-line thingies it should be
just fine...)
