I don't know if the old controllers support multiple motion groups, but I know the newer ones from version 5 (I think) explicitly state with a very serious warning that they do not and bad things will happen.
I know, and I'm aware of that warning.
Programs are working though.
What I was trying to say is that I don't see the MOVE TO instructions in the newer KAREL manuals.
Karel supports motion, even if the newer manuals do not mention it any more. But that is not a problem in this case. Manuals are present, as well as a copy of ktrans.
You can still build programs with motion statements in them. They will just not go as fast as TP programs.
And personally, once you get used to the Karel way of doing things, it is not that bad.
