Hi Greg ... I can see that you've made some more changes to your
personal branch for the new ".setdp" instruction since I last tested
it out ... but those changes still haven't been applied to the CC65
master branch.

May I ask how things are going, and if there's anything that I can do
to help get that new functionality adding into the main branch?
