Running atm, I'll go on trust, if I get infected I'll kick your ass :P
On linux eitherway so I'll have a crack at it.

#!/usr/bin/perl
print \"Enter string [enter character in the string seperated by a dash (-)]:\n\";
print \">> \";
$huhu= <STDIN>;
chomp($huhu);
$i=12;
@gy=split(/-/, $huhu);
foreach $gy(@gy) {
$num = ord($gy);
$num--;
$gy = chr($num);
print \"$gy\";
}
