I ran into a non-split table of 16-bit addresses, each of which was (address-1) for a code location. I wanted to create a label, add a code hint, and set the operand for each one, but there's no easy way to do that. It turns out the split-address table formatter can be made to work for non-split tables with just a few minor changes.
