I believe your attempt to return from a command substitution within a
function is causing rc to get thoroughly confused.  I must admit that I
can't decide whether to be appalled or impressed by your novel use of
this construct!

Getting read right it tricky.  I recommend the read command in the FAQ
(although make sure you have $nl defined -- fixed in the next
version).
