HP-42S x HP-41 short label addressing

[Artur - Brasil]

Hi, guys!

I'm starting playing with my HP-42S (after 20+ years of its launch?!!)

Do you know if it has the short label (A-E, a--e, i, j) automatic assigment to top keys (A--E, I,J and a--e) - as HP-41 has - beyond using Custom menu, with FLAG 72 (that can't be set or cleared by program, correct?) set, which will show on display 2nd line A B C D E XEQ and will branch to respective local labels?

This approach is very primitive, as does not allow me to determine the "soft menu" messages, as it shows A B C D E XEQ always.

Second, if I have to control label 72 by calculator's MODE menu, programmability/flexibility is affected (trying to put SF 72 in programm line will show Restricted Operation).

MENU also is not complete, as it does not allows use of SHIFT labels, correct me if I'm wrong, please!

Any ideas?
