the safest way to do this....

in user.pl include a function that returns a reference to the variable

sub get_userName {
return \$userName;
}

Don't use "require", but "do" as in:

do "/user.pl";

then you will be able to use the veriables defined in user.pl

like I was saying, the safest way is to use the "get" method because then you don't have to worry about variable names stepping on each other

Kavar, you are right. However it depends on what you are doing. For example if you just want to print out the final values of variables defined in a different script, I'd go with the "do" solution.

With using
sub get_userName {
return \$userName;
}

How do I call it from the script?

hmmm, you should be able to use the import function of your package,
if your package does not have an import function, you can use "use"

use Modulename();

Well I consider my answer more fit to the author question (he was trying with "require"...so just changing it to a "do" is much simpler than implementing accessory functions)
