HP41: Updated RUBIK's / CHESS modules

[mstram]

I downloaded the only "CHESS MODULE" that was found on TOS.
and am trying to run it in the v41 emulator.

I started the game with XEQ 'CHESS'

The program seems to work (haven't finished a complete game yet), but the pdf mentions that there are options when it is my move :

But the only option I seem to have is entering a *move*.

I'm interested in knowing how to :
"- Check the board in order to know what piece is where"

Also curiously, the V41 emulator always indicates that it is in PRGM mode (though it does accept "move inputs".

Perhaps, because (as the pdf notes), the program is using "synthetic" instructions ?

Any info appreciated.
