It had to do with (a) global variables in my CDEF source code, and (b) not doing: #include "SetUpA4.h" RememberA0(); <-- in the 'main' CDEF function SetUpA4(); ... RestoreA4(); I'd never used globals in a CDEF before, so didn't know to include this. After I posted the original I thought to call a friend who might help. He did. It now works. Sorry for the inconvenience. steve
