Yes, it should. The issue is that you never really know if
the stack will blast through the 256 byte boundary, unless HAT
checks it.
You generally allocate small stacks, so HAT could be modified to
FORCE the data stack to start at the boundary if allocating it
makes it across the 256 byte boundary...

If you want to design a logo, great! I really mean the LCD.
What about "4th" and standing man?

Yes, a heartbeat or something that toggled when accepting characters
might be cool. I designed it so that users could add these things later.
Something I wanted was to make a "vector" array that you can use
to select one of 10 programs with the "PGM" key and then RUN them...

Great ideas, lets get going!
