Used after a CMP or SUB instruction, JLE transfers control to short-
label if the first operand is less than or equal to the second . (Both
operands are treated as signed numbers.) The target of the jump must
be within -128 to +127 bytes of the next instruction.
Notes: JNG, Jump if Not Greater, is the same instruction as
JLE.
JBE, Jump if Below or Equal, should be used when
comparing unsigned numbers.
JLE, Jump if Less or Equal, should be used when
comparing signed numbers.
