This only jumps the program if the ALU's negative flag is set to true.

如果 ALU 的否定标志设置为真，这只会跳转程序。

If we wanted to test if A was less than B, we can use the ALU to calculate A subtract B and look to see if the Negative Flag was set to true.

如果我们想测试 A 是否小于 B，我们可以使用 ALU 来计算 A 减去 B 并查看 Negative Flag 是否设置为 true。
