I decided to go ahead and make some of the changes.  I will post a new copy
(ASC format) in another couple days when I finish the changes.

The changes I've made so far are the following:
   Made the OFF key turn the calculator off while in TODO (instead of BLUE
	SHIFT [EXIT])
   Made the [EDIT] menu key return the current text as the default value for
	the new text (which also makes it easy to cancel an edit simply by
	pressing ENTER without making any changes).
   Made the program font-size independent (with a table for the font sizes for
	the 3 builtin available fonts) and provided a binding (+ and - keys)
	for dynamically changing the size of the font while the program is
	running.  I did this because the small font is good when you want
	lots of data, but is hard on the eyes since it's all uppercase, so I
	want different fonts at different times (depends on how wide the
	data is I'm viewing.
   Implemented horizontal scrolling (by character, 10 characters at a time,
	and beginning and end of line).  I also increased the width of the
	GROB to 2 screens (adjustable with a local variable in the TODO
	directory).

I also would like to change the LIST mode to be function key driven like the
normal interface, but haven't implemented that yet.
In addition, I'd like to trap the ATTN key using Bill Wickes IFERR routine.

I'll post either when I get all the changes finished or I expect it to be
awhile before I get the rest done (I'll probably post in a couple of days).

Sorry, I was confused.  I withdraw the suggestion.  The lower versus upper
case issue is just convention.  Local variables will only work if the variables
are not shared between functions and they are, so they won't address this
problem.
