Hi lee,
I should note that it is my impression that you are far too needy in your
enquiring, and I'm starting to lose patience.

No, the count of items in the list gets stored in $list: $list == 3

Ken, your mixing your @ with your %
Try this:
#!/usr/bin/perl
&GetMarmots;
sub GetMarmots {
%result = ();
$result{'steppe marmot'} = 4;
$result{'himalayan marmot'} = 3;
$result{'mongolian marmot'} = 1;
$result{'woodchuck'} = 6;
return %result;
}
foreach (keys %result) {
I'm sure this is an easy one but after Googling for hours, I still
don't get it. Given the following subroutine, how do I return the
result array? Nothing I try works.
sub GetMarmots
{
@result = ();
$result{'steppe marmot '} = 4;
$result{'himalayan marmot'} = 3;
$
