Thank you John
Why do I need
use warnings;
use strict;
It works without them:
with them i get:
Global symbol "@list" requires explicit package name at ./obj14-2.pl
line 7.
Global symbol "$item" requires explicit package name at ./obj14-2.pl line
10.
Global symbol "@list" requires explicit package name at ./obj14-2.pl line
10.
Global symbol "$item" requires explicit package name at ./obj14-2.pl line
11.
Global symbol "$item" requires explicit package name at ./obj14-2.pl line
14.
Global symbol "@file" requires explicit package name at ./obj14-2.pl line
15.
Execution of ./obj14-2.pl aborted due to compilation errors.
Thanks
As you can see you don't *need* them, however you should use them to help you
find problems with your code.
