The # operator will work as expected only when the tables are
well-formed arrays (which means that #t == n implies that values at

your case the indices are actually strings (besides the fact that they
don't start at 1). The fact that you consider this to be an oddity
means that you most probably need to read the manual on this issue
very carefully.

Hello,
Thanks for the reply.
You are correct I didn't understand the operator only worked for arrays
and not dictionaries/hashes. My bad. I understood that it only worked
for well formed tables, but neglected the understanding that it was for
arrays only.
As to it being an oddity. It was a question not a statement.
I was fully aware my understanding of the issue was by far the leading
potential error.
Thanks for the lesson. It helps. And I do need to read the manual some
more. Just trying to apply what I've learned or think I've learned in
between readings.
