Thank you to all of you who responded to my question about pasing hashes
into a function. The -> operator did the trick.
My problem was that I thought once I passed the hash in, I could
dereference it That doesn't appear to work like I expected.
sub mod_hash {
my $hash_ref = @_;
my %hash = %$hash_ref;
$hash{key} = 0;
etc,etc,etc.
It appears that that just makes a local copy of the hash, then disposes of
that copy at the end of the subroutine. I think I kind of understand why
this doesn't work.
Thanks again for you help,
John
