The warning is telling you to add the package name to the variable which in this case is probably main. use strict; $main::strg = 'A string'; $main::strg2 = 'a second string'; Which can be shortened to: use strict; $::strg = 'A string'; $::strg2 = 'a second string'; > unless I declare the variables like: > my $strg = "A string"; > my $strg2 = "a second string"; Perhaps this article may help you understand. http://perl.plover.com/FAQs/Namespaces.html John -- use Perl; program fulfillment -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
