So, once again, does anybody know how do use bitwise operators on the
hp48?  I am referring to bitwise operators that operate on binary numbers
and not the ones that operate on hex-strings.

There seems to be only the bitwise AND available in the ROM (#AND 03EB1),
for OR, NOT and XOR you can use the code obs below:

OR:
CODE
    GOSBVL =POP2# 03F5D
    A=-A!C A
    GOVLNG #03DC7
ENDCODE

NOT:
CODE
    GOSBVL =POP#  06641
    A=-A-1 A
    GOVLNG #03DC7
ENDCODE

XOR:
CODE
    GOSBVL =POP2# 03F5D
    R0=A
    A=A&C  A
    AR0EX
    A=A!C  A
    C=R0
    A=A-C  A
    GOVLNG #03DC7
ENDCODE

Bye,
