Put the following line in the main script: our %hash; Change the "my %hash = ( ... );" declaration in lib.pl to "our %hash = (...);". In your original versions, %hash was a lexical variable in lib.pl, and thus not in scope within perl.pl. Using 'our' instead of 'my' makes %hash a package variable (in package main::), and as such is accessible by both perl.pl and lib.pl, The 'our' declaration also lets you leave off the package name when you access the variable. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
