RE: hash return from a sub

Ill make a guess it's a scope issue, but cant be sure without the main
code.

Try something like

use strict;

my %test=mysub();

print %test;

sub mysub {
my(%myhash,$var1,$var2);
$var1 = '1';
$var2 = '2';
$myhash{$var1} = $var2;
print %myhash;
return ( %myhash );
}

This works fine from testing.

Subject: hash return from a sub

How can i return a copy of the hash? (The hash is build correct, but
return alsways null) Here a sample of my code:

sub mysub {
while (.....) {
var1 = ....;
var2 = ....;
$myhash{$var1} = $var2;
}
print %myhash; # all ok until here
return ( %myhash );
}

%test=mysub();
print %test; # wrong, don't print nothing, neither error;

I would like to return a copy of the hash to a new variable, not a
reference.
Thanks in advance.
