希望您使用新的SYSIBM函数路径，既便您没有使用字符串单元参数也是如此。

You are expected to use the new SYSIBM function path, even when you are not using the string unit argument.

注意：新的字符串函数位于SYSIBM函数路径下，而旧一些的函数位于SYSFUN路径下。

Note that the new string function is under the SYSIBM function path, compared to the older functions under the SYSFUN version.

如果路径与文件对应，此函数将检查文件的大小是否等于0。

If the path corresponds to a file, this function checks whether file size equals 0.

so we're going to use this concept of the path to go from the initial point to the end point.

在处理状态函数时,路径的选取。

Now remember, we went through before how it's a state function but to calculate it, you'd need to find a reversible path, along which you can figure this out.

请记住，我们不需要知道它是怎样的一个态函数,只计算就可以了，你需要找到一条可逆路径，沿着这条路径就能算得这个结果。

s We are back over to E as a function of n, l, m and s, only we got there through this other torturous route.

我们回到将E作为函数n，l和，只要我们解决了这个烦人的路径。
