    I have 
    $a = "dfowusgfiwu42394353****hsdfsd";
print "$a\n";
$a =~ s/!([a-zA-Z0-9])//g;
print "$a\n";

    what's not right? it doesn't do anything to the string... and I know it looks useless, but it's a test for something else. what I want is to delete any and all characters from a string that don't fit into [a-zA-Z0-9]... unless things like "$(@$&%*" are in there...
