Can someone shorten this upper routine?
sub toUpper
{ my $z = shift;
$z =~ tr/a-z/A-Z/;
return $z;
}Also in a slightly different scenario, how can i change the value of the parameter itself with a sub. $a="ca"; toUpper($a); #change the $a value itself print $a; #I want it to print "CA" ----------------------------------------- eMail solutions by http://www.swanmail.com -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
