*What not just like below? As long as you have unique key, it would
retain all the information.*
$ex_psc{"$excpsc"} = "$keyword";
$ex_psc{"$excpsc"} is superfluous because *all* hash keys are strings.

What’s wrong with always quoting "$vars"?

Thank you John,
Also, can you explain why below is wrong?
Otherwise, besides slowing you down, you're going to break
code when the thing in the scalar is actually neither a
string nor a number, but a reference:
func([EMAIL PROTECTED]);
sub func {
my $aref = shift;
my $oref = "$aref"; # WRONG <----- why is it wrong?
}
