Hi, Michael. I had some trouble with getting variables into registers, as well. I can think of three ways: 1) Pass the variable to a function - the first function argument seems to be r0. You can easily experiment with this by inspecting the (...) (21 years ago, 18-Jan-04, to lugnet.robotics.rcx.legos)

I hate to see questions go unanswered.

(...) I wrote WORDS and SEE and some other useful stuff for pbforth 1.21. SEE is a bit rough, it doesn't handle IF, LOOP etc. very graciously but just dumps out bytes.
