New third party firmware (Not HP'PRIME TEAM)

Adding GOTO to PPL would be "hard" even for HP, so I (unfortunately) would not hold my breath waiting for a 3rd party hack to do it.

PPL programs are not a linear sequence of unrelated instruction, but a non-linear tree of instructions sequences. This makes it hard to do a GOTO as each sub-sequence has temporary data associated to it and doing a GOTO would force the GOTO instruction to be able to detect if the destination is in the tree, and then properly destroy and initialize the right sub-sequence temporary data (including local variables creation).

True but if the entire firmware could be replaced with an HPPL (extended?) interpreter, it wouldn't have to follow the same implementation logic as the stock version.
Hmmm. A thought. HPPL is fast enough that I could write my own BASIC interpreter using it and still have plenty of horsepower left to run serious programs. Well, it's off to my coding zone!
