rob76, yes, that was my earlier post. I thought about just continuing that thread but most of the discussion was troubleshooting the robot itself as we thought it might be out of memory or in the wrong mode or something of that nature. However, I was able to get one of the example programs to work (the Pick and Place for Beginners tutorial program) and it allowed me to touchup points there, but still not in any other program. Thinking that my problem must just be with my program itself and noticing that the DATA KAREL Posns window was empty for my HELLO_WORLD program, I figured I had isolated the issue and thought it would be best to create a new topic to discuss it... after spending a bit more time with the robot, though, I'm not confident my assumption that points need to be stored in that DATA KAREL Posns window is correct, as I just checked and saw that it shows no positions for the tutorial program either.
Thanks for the willingness to help though!
I'll keep looking for what is causing my problems... if I find it I'll probably post in the old thread since you're right in pointing out that that backstory to the issue might be important.
