It doesn't know, but it doesn't need to

Yes,
Thanks for the instructional videos, Birt! The general Forth-y bits of it
have been helpful and If I had a C=64 kicking around I'd definitely give
DurexForth a try.
The problem with .S is that if the stack has underflowed, it just keeps
reading past the bottom until I assume it wraps all the way
Well, I now have a fairly clean M100 PCB (using the glycerine and alcohol
recipe), but no change on the LCD status (still not displaying on this unit
though it works on my 8201a). More digging in my future.

It will never show you more or less than what is on the stack. If what is on
the stack does not make sense it is because of an error in programming and this
is very, very easy to do.

debugging tool, and not used by programs so it doesn't impact performance.
I’m not sure how that would work since .S has no idea what you think should be

I didn't see one around anywhere(*), so if anyone wants, there's a y2K

(*) There is *a* rom in VirtualT that claims to be for M10, but it's no
good.

Hi,
That's sounds quite interesting. I learned vi when I was jumping between
different Unix systems, and figured they would always have vi. Not always
true, especially now, but my hit rate was better than with emacs.
