Edit: I did a fast test,
"HEPAX 1D" with pre-2020 NoV firmware works, but
"HEPAX 1D" with 2020+ NoV firmware has the issue.

This is a resurgence of an old HEPAX emulation quirk, found in many emulators in the past.

As pointed out long ago, the "problem" can also be reproduced on a real 41C/HEPAX system with the help of the HP-IL devlpt ROM.
(or on latest V41 if you don't have the physical modules - V41 is now very accurate).

With the HP-IL dev ROM and HEPAX installed, do XEQ "ON",
- then enter a XF or alike command in a program, and check the entered line,
- or in run mode, execute HEPAX 000, then try to CATALOG the HEPAX functions (particularly funny on a halfnut 41CX)
