I would make it 43, although as that matches your new image, perhaps 42 was just a typo.

I've gone over it again, and I still count only 42 assignable positions:

Code:


    6 f A-F (shifts and rotates)
    6 g A-F (LJ, shifts, and rotates)
    2 MASKL, #B
    1 MASKR
    2 RMD, DBLR
    2 XOR, DBLdiv
    3 SB, CB, B?
    2 AND, DBLx
    1 NOT
    1 OR
    1 WSIZE
    2  <, >
    4 SHOW HEX, DEC, OCT, BIN
    6 A-F
    3 SET COMPL 1s, 2s, unsigned

If you think there's a 43rd, let me know where.

I conider the complement mode to be the least desirable, and the unshifted A-F to be the next least desirable, but in principle I can reassign them in FLOAT mode.
