in thread when is "my" not necessary?

Use a hash and don't abuse globals just to pass arguments. to paraphrase your code: 

#!/usr/bin/perl -w
use strict;
check(qw(a b c));


sub check {
  my %hash = (
   a => 'here',
   b => 'present',
   c => 'me too',
  );

  for (@_) {
    print "$hash{$_} has a value\n";
  }
}

    Thanks... ephiphony moment. I'm convinced to use strict refs and eliminate any symbolic usage.

    package x actually is a static cache of prefs stored in a database refreshed only when those prefers are updated by a user.

    Doing my stunt (above), I'm now using a hash to store all form fields and simply checking presence using the x list for that preference.

    Thanks-Thanks.
