Instead of saying $fmail$cnt try saying ${"fmail$cnt"}. This uses references, but not the kind that involves an address of memory. Instead you're referring to a variable by name.

This kind of calling convention will break use strict however so it is something that I personally steer clear of.

Another approach would be to create a hash and store your fields in there e.g.:

  my %fields = ( fname1 => 'John',
                 fmail1 => 'john.lizmore@something.com',
                 fname2 => 'Lisa',
                 fmail2 => 'lisa.lizmore@something.com'
               );

Update: thanks to Transient for pointing out an error in my variable name.

Update2: merlyn says PLEASE do not suggest to people to use softrefs! I downvoted your node for that. How kind of merlyn to send me that message. I do want to point out that I believe merlyn did not read this article, as I also discourage the use of softrefs. As a result, to assist some of the skim-readers on this site, I have gone back and bolded the appropriate statement.
