So, what your saying is patch the edit command to map in the wasted 7376
author bytes with the new code put there and jump into that segment. Is it
possible to fit a screen editor into 7376 bytes? What does a screen editor
need to do to make it nice enough?  Things like cursor key movement. How
much interfacing to Extended Color Basic is required for it to work?
