There are two types of CALLS and JMPS in 16-bit assembly: near and far.
在16位汇编中有两种类型的CALLS和JMPS：near和far。
Near contains a 16-bit offset. For calls it will save the IP only.
Far contains a segment and a 16-bit offset. For calls it will save IP and CS.
Near包含一个16位的偏移量。对于通话，它将只保存IP。
Far包含一个段和一个16位偏移量。对于通话它将保存IP和CS。
Defining a proc as FAR tells the assembler that all Calls to that proc must give both a segment and a 16-bit offset. The upshot of this is that the FAR Call will save both IP and CS. There are two variants of RET: RETN and RETF. One will pull off IP and the other will pull of BOTH IP AND CS. Go figure which one, okay?
定义一个proc为FAR告诉汇编程序，该proc的所有调用都必须给出一个段和一个16位偏移量。这样做的结果是FAR呼叫将保存IP和CS。 RET有两种变体：RETN和RETF。一个将拉动IP，另一个将拉动IP和CS。去判断你的是哪一个，ok？
