So you mean that if you edit a series of [Space] characters and press ENDLINE, the system should not declare any errors.

but if instead the error appears, it means that a strange character like [)], [?], [$]

When I am present I will do this test directly on the computer.

For now can I simulate this on the HP87 Emulator?

I have tried it on the emulator and this error actually appears.
It seems that the mysterious character [!, ", $,%, &, /, (,), =,?, ....]
is the first on the command line.
because if it were the last it would give a different error

example
(Q => ERROR 88 BAD STMT
Q) => ERROR 89 INVALID PARAM

for this reason I suggest that it is the first character of the command line to be indicted.
Obvious to Video with the broken computer I don't see any strange characters in the monitor.

I think this is the way forward



thank you very much J-F Garnier
