- the sequence: MENUSWAP {"ABC"} TMENU masks the variable menu, and I don't know how to recover it.

The VAR key... except we don't have any yet.
In the meanwhile, you can use menu codes with TMENU.
The VARS menu is << #40000h TMENU >>.

When the display object is a program, the program is executed every time the menu is displayed. Changing the flag doesn't automatically refresh the menu, but ending your program does. Unless you FREEZE (not implemented yet) the screen, everything gets updated when the calculator goes idle.
If you set the flag and run a long loop, you won't see the menu updated immediately.

That's by design. You either provide a program, or a list { display decoration } ready for display. A list containing a program is not a valid combination (the program is displayed as-is, not evaluated to prevent infinite loops).
If you provide a program, then the program is supposed to take care of everything, including the decoration. Nothing prevents the program from returning a list { display decoration }, which will be processed in the usual way.
So you don't put a program in { display decoration }, you make a program that returns {display decoration }.

Only the directory and inverted are implemented for now, no checkmarks yet (I need to design a nice-looking tick mark).
The numbers are bits, so 1, 2, 4, etc. 1=directory, 2=inverted, (and their combination 1 OR 2 = 3, inverted directory) and that's all I implemented so far.
