in thread more fun w/ HASh ref's

Consider the following code snippet:
my %options; my $options->{'heredoc'} = '1'; my $config_copy = ReadINI ($copy,%options);

What this is actually saying is annotated below.

# Create a hash called %options my %options; # Create a *scalar* variable called $options and then try # to use it as a reference. Since it's just been created, # it's undefined. Hence this won't work. my $options->{'heredoc'} = '1'; # Call ReadINI passing it $copy and your %options hash. my $config_copy = ReadINI ($copy,%options);

I imagine that the line you want to have in the middle there is:

$options{heredoc} = 1;

It's a hash look up. %options is a hash, not a hash reference. If its not a reference, you don't want the arrow.

I hope this helps.
