[PD] More Questions about Documentation

[Jim Aikin]

On further inspection ... I'm looking at 2.control.examples / 15.arrays, 
and it is frankly not at all helpful. Many things are not explained 
here. And when I create an array, the Help file is even worse. It refers 
to "Table", not to arrays at all.

In the control.examples window, I see functions like sinesum and 
cosinesum, but there is no indication of whether other such functions 
might exist, or what arguments they might want to see. I see a command 
for reading a text file, but with no documentation as to what format the 
text file should be in. And then there's the lovely sentence, "Arrays 
live in graphs and graphs may hold more than one array...." Sounds 
interesting, but what does it mean?

Did I just not download the real manual? (Like, the one with the index?) 
Or is this stuff really not explained anywhere?
