I just tried few experiments WITHOUT rem and it works, always.
This justifies my theory.
REM is not needed because we ALWAYS return to a safe memory location, since we were in basic prompt.

Paul I am in the extremely happy position to announce you that
YOUR ROM WORKED!
I successfully connected line A13 from the eprom to the bus and your rom WORKED like a charm!
That is like a dream! FIREWORKS
The VLA81 came yesterday.
I honestly didn't expect your rom or my direct connection of A13 to the cpu to work.
Would you be kind enough to add those 5 instructions somewhere in your rom so I get a black background each time I initialize my homebrew zx81 compatible super computer?
