你说“检查”价值是什么意思？如果你正在调用另一个页面中的子例程，并且希望在返回时恢复pCalthe，只需把它放在那里：没有读取PCL的点，你将总是得到读取它的指令的地址。

以下为原文
What do you mean "check" the values?
If you are calling a subroutine in another page, and want to restore PCLATH on return, just put:
pagesel $
There is no point reading PCL, you will always get the address of the instruction reading it.
