LT               Less Than Relational Operator                  MASM Operator

expression1 LT expression2

Returns true (0FFFFh) if expression1 is less than expression2,
otherwise 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).
