The "our" declaration is for the current file only, so you need "our" in Script 1. $a is a "special" variable (used in sort blocks), so it gets a "free pass" from use strict, just like all the other special variables ($_, $/, etc.). Generally, experts would advise against using $a and $b as variables in your programs. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
