Hi,
I read a tutorial on lambda on line. I don't think that I am clear about
the last line in its example code. It gives two parameters (22, 23).
Is 22 for n, and 23 for x? Or, it creates two functions first. Then,
each function gets 22 while the other function gets 23?

Certainly not impossible: you could write your own wrapper function:

It sounds to me more like it is possible to use long file names on windows
