Bob,

I agree - I've coded screen processing this way (only using the aid byte
or INKC ever since the leave and iter opcodes appeared.  although
usually I would use a select/when group to process all other function
keys as well (some would leave after processing, some would iter)

I think it makes the code very clean and readable

But on the other hand, I don't want to start another "LEAVE and ITER are
just pretty GOTOs" argument :)
