That sounds nice, but it's actually a horrible idea, because if GTO Znnn is in the program, and you delete program line Znnn, the GTO now points to the wrong line (namely, what had been the line after Znnn before the edit). Every time I try to debug by trial and error on the 35s, the GTO's get all out of whack. Horrible idea.

Agreed. After being stung many times by wrongly renumbered GOTOs plus unreliable checsums and other nasty bugs, including unrecoverable locks ultimately resulting in losing all (hard-to-key-in) programs and wasting tons of my time, I gave up and tossed the HP-35s in a drawer, where it rests unused for the last 15 years. A pity, I initially liked it but its many important bugs and flaws ultimately killed it for me.

That's what happens when HP forgets about decent quality controls and further doesn't ever fix the bugs: what shoud have been a very nice calc goes down in shame, directly to oblivion. Another example woul be the "über-buggy, utterly unreliable toy", many of them also indefinitely gathering dust, but that's another story.
