Hi Aad,

I think, I know your problem:

All programs on a micro consist of a main loop forever !
Means a micro should never finished.

But on your code after POP PSW the program run into uncolonized area, no more real code exist and only crazy things can be done.

So any program must have a RET or JMP before the END statement.
And there must also be a known location to return or jump to continue.
