I cannot say much about the HP65 diagnostics program, but the "-" on the HP65 is displayed when all 100 steps are occupied so that adding one more step would delete another one. Delete one step and the "-" disappears.

Ah, that's clever. Thanks for enlightening me!
Are there different rom versions that display the - in different positions?
