    Hi Russ,

    Not particularly "Sneaky" ... but it's "Quick".
    Code:
    Counter  VAR BYTE BANK0
ODD      VAR Counter.0
TestWord VAR WORD BANK0

ASM
    clrf   _Counter
    btfsc  _TestWord,0
    incf   _Counter, F
    btfsc  _TestWord,1
    incf   _Counter, F
    btfsc  _TestWord,2
    incf   _Counter, F
    btfsc  _TestWord,3
    incf   _Counter, F
ENDASM

If ODD THEN
  ; ODD number of bits in the TestWord<3:0>
ENDIF
