Do I have to export all variables and functions from my PM file?by SergioQ (Beadle) |

SergioQ has asked for the wisdom of the Perl Monks concerning the following question: My Perl PM has the following lines of code:
And I've wondered if I must export functions, strings, arrays, etc. etc. that are not used ouside of the PM module? Obviously I have already played with it both ways, and I have had no headaches. But that doesn't mean it's the proper way. So that's my question: If I don't use a specific variable outside the PM itself, do I need to export it? That includes an array, which the PM might return an array reference to the calling perl script. My limited knowledge of Perl recalls that Perl knows if a variable is still in use and will keep it alive if necessary, but again, I learned only as much Perl as I needed to get some very limited scripts written. Thank you
