Hi, Trying to create a little script that can be set up easily for use again and again for checking submitted Form Data. This works, but I just wanted to know if theres anything I could make more efficient? 
#!/usr/bin/perl
use CGI;
use strict;
my $q = new CGI;

print "Content-type: text/html\n\n";

#GET VARIABLES FROM SUBMITTED FORM
############################################
my %form    = (var1   => $q->param('var1'),
               var2   => $q->param('var2'),
               var3   => $q->param('var3'));

#SET ARRAY WITH REQUIRED FIELDS
############################################
@reqform    = (var1,var2,var3);


#CHECK THAT REQUIRED FIELDS FILLED else PRINT ERROR
###################################################
foreach (@reqform) {
  if ($form{$_} eq '') {@errormsg = (@errormsg, $_);}
}
if(@errormsg) {
  &PrintError;} else
  {&CARRY_ON_PROCESSING_FORM;
}


#PRINT ERROR
###################################################
sub PrintError {
  print "<html><body>";
  foreach (@errormsg) { 
    print "You need to enter something for <b>$_</b><br>";
  }
}
