I somehow disabled the functions COMMAND and UNDO. Can somebody tell how they can be enabled again? Wich flags should be turned on and how?
The 28S has a MODE menu where you can enable various settings, including COMMAND and UNDO. I don't know whether this is controlled by flags.
Flag 31 enables LAST.
I can only guess that the 28C behaves the same way.
Hi!
UNDO & COMMAND are keyboard only on the HP-28C/S.
Cheers
