In that case, the answer is relatively easy. That's poor perl programming. You never (with a 99.9952334% probability) will ever need to do that. It is a) bug prone b) often a security hole c) better solved with a hash or an array The reason the syntax exists is buried somewhere in perl4 or earlier. (And perl rarely removes things from the langauge.) -R **Majordomo list services provided by PANIX <URL:http://www.panix.com>** **To Unsubscribe, send "unsubscribe phl" to majordomo@lists.pm.org**
