GT               Greater Than Relational Operator               MASM Operator

  expression1 GT expression2

    Returns true (0FFFFh) if expression1 is greater than expression2,
    otherwise it returns false (0000h).

       Notes:     The expressions must resolve to absolute values.

                  This operator treats its operands as 17-bit numbers.
                  The 17th bit specifies the sign bit, thus the largest
                  number possible is 0FFFFh (65,535).
