N
After the operation, if bit 15 of AX is 1 then the negative flag bit is set; otherwise
it is cleared.
Z
After the operation, if AX is 0, then the Z bit is set, otherwise it is cleared.

This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.

; Complement the contents of VarA:
MOV AL,@VarA
; Load AL with contents of VarA
NOT AL
