I recently pulled a basic program from "sources," and tried to 
adapt it for Atari Basic (Yech).  It bombs out with a "Too many 
FOR loops" error.  What does it mean?

Does Atari basic look for certain types of errors before it 
begins program execution?  The first program line contained 
"FULLW 2" and CLEARW 2," but neither happened.  Just the error.

Is there another BASIC available for the ST?  I really don't like 
working with the windows.  Every program I've written in basic 
has a couple of false starts when I clear windows or change 
window sizes.  I would rather have full screen outputs without 
the framed in appearance of the window.

Thanks
