Hi I did a search for "canon cat" with google in the news groups and found the trick to enable Forth on the Cat. There was a note from Derek Peschel that discribed it well enough that I was able to figure it out. It has two Forth modes. One uses the Forth engine to calculate things from the text of on the page. The next level of mode drops you into a Forth interpreter. It seems to take most Forth commands but I tried things like vlist and words but these were not part of the vocabulary. I'd like to see what its vocabulary is but it may not have a word defined to do this. It does have such words as C@ and @ as well as it compiles new words. This means I can do some exploring. I didn't try it but I think I can even use the text input as source from the first level. Dwight
