Writing out to a file and cdiff

[Jeffrey Duda]

I have two questions.

1) How do you write data out to a file in text format?  I know there is an
fwrite command, but I don't really know how it works.

2) Can the cdiff command work when three environment dimensions are
varying?  I'm trying to compute EPV, but to do so, I need to do a cdiff
command in the x, y, and z dimensions, but I always get an error and usually
Grads crashes when I do it.
