Some observations:
- The code doesn't compile. It's missing a semicolon.
- Modules must return a true value, or else perl will think something's wrong with it and refuse to continue.
- The name of your module shouldn't be all lowercase, or you risk clashing with some future Perl pragma.
- I don't think you need a BEGIN block
- It's better to use our instead of vars.
For passing the hash to the sub, you can use a reference. Try this module...
## file: Myperl.pm
package Myperl;
use strict;
require Exporter;
our $VERSION = 0.1;
our @ISA = qw(Exporter);
our @EXPORT = qw(getInfo);
our %EXPORT_TAGS = ();
our @EXPORT_OK = qw();
sub getInfo {
my $thescalar=shift;
my $thehash=shift; ## pick a reference
print "scalar: $thescalar\nhash:\n";
print "$_ => ", $thehash->{$_}, "\n" for keys %$thehash;
}
1;
...with this code:
use Myperl;
my $s=4;
my %h=(0..5);
my $myresult=getInfo($s, \%h); ## pass a reference
