for your first question (exporting variables without
our, one option is explained by jarich
above. A second option would be to fully qualify your exported variables with the package name, as in:
package I_am_an_example;
use strict;
use vars qw(@EXPORT @ISA);
use Exporter;
@ISA='Exporter';
@EXPORT=qw($jimmy $bob);
$I_am_an_example::jimmy="White";
$I_am_an_example::bob="Hope";
1;
Your require does not work because with use strict;, you need to declare the scope of your variables. To pull in the incl.pl as above, you would do:
use strict;
use vars qw($test1 $test2);
require ('inc.pl');
print "$test1\n$test2\n";
Also, see the faq on the differences between use and require.
