FORTH for the HP 50G

I have several Forth systems that I can test with Dosbox, and they all give -32768 as a result for this operation, which seems logical.
The standard however doesn’t precise the behavior, if I understand correctly:

What is the defacto standard for this? I've also noticed some list new words and some list all.

Again, all the Forth system I know give the entire list of words.

I don't know how lbforth is built. I see that WORDS is defined in this file:
https://github.com/larsbrinkhoff/lbForth.../tools.fth
Does that mean that only a few words are available, and that other words must be compiled?

I've noticed that when Forth is terminated with BYE, all definitions are lost. Maybe it's expected, but it's not convenient
