That's not what `cmp` is for. It's the string equvilent of `<=>` and is meant for use in sorting operations. In this case, it won't work at all as shown, because it returns 0 when the two strings are equal (`unless( $a cmp $aa)` would work, but there is a better way). What the OP really wants is `eq`. ---- send money to your kernel via the boot loader.. This and more wisdom available from Markov Hardburn.	[reply] [d/l] [select]
