Re^3: Exporting scalars from a module

    How can I enable use strict and not use my to declare the variables? (The version of perl we use does not support the our keyword):

    package ExitCode; my @varsToExport = qw(%exitCodes $EXIT_SUCCESS $EXIT_GENERAL_FAILURE $ +EXIT_CHANGELIST_CONSUMED $EXIT_FUTURE_CHANGELIST); require Exporter; use vars (qw(@ISA @EXPORT), @varsToExport); @ISA = qw(Exporter); @EXPORT = qw(@varsToExport); %exitCodes; # Define exit codes $EXIT_SUCCESS = 0;
      You need to put your @varsToExport in a BEGIN block.
      my @varsToExport; BEGIN { @varsToExport = qw(...); } use vars @varsToExport; @EXPORT = qw(@varsToExport);
      Or you can upgrade your perl. :-)

[atcroft]: james28909: Make both hands into fists, place them together (with thumbs concealed), and every knuckle is a month (starting with Jan.) has 31 days, every dip (between knuckles) does not....
[atcroft]: (And Feb. is the odd case, because it is 28, unless it is a year divisible by 4, or if it is divisible by both 100 and 400 (at which point it is 29).)
[james28909]: i know but scroll through your calendar on your computer.
[james28909]: i thiught you were going to say make both hands into a fist and puch yourself in the face
[atcroft]: .oO(Sorry, I probably should have said take two normal hands....)
[atcroft]: james28909: No, unless you are a politician, I wouldn't say that (and even if you are, I still probably wouldn't say that).
[james28909]: i mean how hard can it be? its just subtracting days lol
[atcroft]: james28909: What about October 5, 1582?
[stevieb]: atcroft: "Make both hands into fists..."... is something my Ma taught me in our native lang, but I was to ignorant and young to pay attention. Thanks for that :)
[atcroft]: stevieb: Sad to say that I only recently learned that particular trick, but I have since found it very useful.... :)
