Bare word files handles (like SUMMARY) are a hold over from earlier versions of Perl. The have a few drawbacks: global scope, difficult to pass between functions, etc. The new (well, newer, they have been around since 5.6) lexical file handles (like $SUMMARY) are much easier to use, have a specific scope, auto close when they are garbage collected, and can be passed easily between functions. You may want to read the docs for open*, IO::Handle** and IO::File*** for more information. * http://perldoc.perl.org/functions/open.html ** http://perldoc.perl.org/IO/Handle.html ***http://perldoc.perl.org/IO/File.html -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
