I remember not only running commands while debugging. I remember moving the program counter back, until a statement above my breakpoint, making live changes in the code and stepping it again until the breakpoint to see the effects of my changes without needing to restart the program.

Yes, but as i wrote "though it wasn't fully editable as many changes requiring restarting".

FWIW this was actually something you could do in QBasic too.
