(...) [...snip...] (...) I defined the BYE word in h8hforth.asm according to Kekoa's comments and it works like a charm. The RCX is reset but doesn't turn off, so new firmware can be uploaded immediately. Ernst (24 years ago, 23-May-00, to lugnet.robotics.rcx.pbforth)

(...) Thanks. That helps. Case sensitivity is good but requiring upper case for hex is annoying. I suppose this is forth standard. That is one thing that I find annoying about forth, that most builtin words are upper case. It reveals the age of (...) (24 years ago, 23-May-00, to lugnet.robotics.rcx.pbforth)
