My Perl PM has the following lines of code:

our @itemsArray = qw( sheet_no sheet_name item );
our $itemsArraySize = @itemsArray;
our @itemRecords;

our @ISA = qw(Exporter);
our @EXPORT = qw(    getTopHTML
                    getBottomHTML
                    ssPrintTable
                    $domainname
                    msgInTable
                    LogInToDB
                    LogOutOfDB
                    createRandonNumber
                    createRawDB
                    printLine
                    alertSupport
                    insertItem
                    getRecords
);

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
