Michael,
My student tried to use parts of your example (see below), but it wasn't
working and I thought that maybe you had a different keyboard. Even the
number keys wouldn't work with their ascii number. But then I tried myself,
typing in your example exactly. It still didn't work. I now know why. My
student, David, doesn't want to have a button on his field so I was trying
to run the starting program, GO, from the command center (is that what it is
called?). I see now that you said to have a GO button and that way it does
work. Why won't it run from the command center? Just curious.
I made a fun program with your example as a start. I added some effects and
varied it but it was a useful starting tool. I might give it to some kids
and see where it takes them.
Thanks so much for your help.
