HP-15C: Fixing the CHS and Stack Lift Bug

[J-F Garnier]

Eric, is the fact you accessed this thread an indication that you are considering fixing this "bug"?
If yes, you may also consider these ones:

GSB I with I<0 doesn't jump correctly
thread-196480.html

If a program ends with a conditional test that is evaluated false,
program pointer skips to line 1 and continue from there, instead of stopping at line 0.
thread-210753.html

But maybe you already spotted them...

Side note: each time I feel sad when see references to Mike (Stgt)'s posts that were arbitrarily and deliberately deleted. What a loss, this was history.
