Used after a CMP or SUB instruction, JGE transfers control to short-
label if the first operand is greater 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: JNL, Jump if Not Less, is the same instruction as
JGE.
JAE, Jump if Above or Equal, should be used when
comparing unsigned numbers.
JGE, Jump if Greater or Equal, should be used when
comparing signed numbers.
