NE               Not Equal Relational Operator                  MASM Operator

expression1 NE expression2

    Returns true (0FFFFh) if expression1 is not equal to expression2, else
    returns false (0000h).

       Notes:     The expressions must resolve to absolute values.

                  This operator treats its operands as 16-bit numbers.
                  Expressions with the 16th bit on are negative. Thus  -1
                  NE 0FFFFh  is false.
