The FAQ has an answer for this: "What's the difference between require and use?" Check http://www.perldoc.com/, and look in perlfaq8. The skinny is this: 1. require() happens at run-time, and either takes a bareword module name or a path to a file (not necessarily a module) 2. use() happens at compile-time (so putting it in a function doesn't "help") and it involves require()ing a module and then calling its import() method -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ ** Look for "Regular Expressions in Perl" published by Manning, in 2002 ** -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
