Home: Perl Programming Help: Intermediate: Using perl modules proving frustrating

clearwaternw New User Feb 19, 2010, 8:03 AM Post #1 of 3 (249 views) Using perl modules proving frustrating Can't Post My modules don't always seem to work... relatively simple tasks being done and my program will quit running as soon as there is a subroutine call to something in a module. I have someone here who has managed to get perl modules working but only with every single scalar lexically scoped with my. They won't read global scalars from my main script. Any advice on the most efficient way of working with module subroutines? I feel like I have to pass and return 10+ scalars every time I make a simple subroutine call... makes it seem worthless to even have these subroutines.

Every time you create a global variable in your code, the person sitting next to you should bash you in the knee cap with claw end of a claw hammer.
