in reply to pattern match showes true

!= performs a numerical comparison. Since both DISK:\db2_backup\ and USEREXIT evaluate to zero in numerical context, they are numerically equal.

You want ne which performs a lexical comparison.

      $siebdb = 'somekey';

$preprod->{$siebdb} = "DISK:\\db2_backup\\";
$prod->{$siebdb} = "USEREXIT";

if($preprod->{$siebdb} ne $prod->{$siebdb}) {
   print "NOT EQUAL";
} else {
   print "EQUAL";
}
