当完成该函数之后，使用返回指针回到原来的位置并继续程序。

After the function has been completed, the return pointer is used to go back to the original location and the program can continue.

从调用函数处返回指针后，将在指定的返回指令指针处恢复执行。

Upon returning from the called function, execution will resume at the saved return-instruction pointer as specified.

这是通过输入足够的数据来用伪数据覆盖参数，及输入到不同函数的新返回指针来实现的，现在就执行新的函数了。

This is done by entering just enough data to overwrite the arguments with dummy data and a new return pointer to a different function; the new function is now executed. 10

It says, if I want to print out something I built in Cartesian form up here, says, again, I'm going to pass it in a pointer to the instance, that self thing, and then I'm going to return a string that I combine together with an open self and close paren, a comma in the middle, and getting the x-value and the y-value and converting them into strings before I put the whole thing together.

这不仅仅是个列表,它是怎么来做的？,流程是：如果我想要返回,一些已经在笛卡尔模式下建好的值，好，再说一遍，我首先要传入一个,指向实例的指针,也就是，然后我会返回一个,由开括号，闭括号,中间的一个逗号,以及提前转换为字符串格式的。
