Create a module like this: Common.pm --------- package Common; use strict; use base 'Exporter'; our @EXPORT = qw/$foo @bar %baz/; 1; Now, in each of your modules, add "use Common;" The variables $foo, $bar, $baz will now be shared globals across all the modules that "use Common". Changes to the value of one of these in any module will be visible across all the modules, since they are all aliasing the same set of variables. (If you already have a common module used by all the other modules, just add the "use base" and "our @EXPORT" lines to that module.) perldoc Exporter (be sure to read this to learn about other options, and why the practice of using @EXPORT is generally discouraged). -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
