You mean the picture of the fit? The current windows version allows
copy and pasting into word from powplot. Brian Toby's 'expgui' gives
other options. The GSAS2CIF program dumps the obs and calc patterns to
an ascii file which you can plot with whatever program satisfies you.

Try reading "gsasnews.txt" in the distribution. Or scanning the
rietveld mailing list archives
(http://www.mail-archive.com/rietveld_l@ill.fr/). The latest manual is
very close to being up to date, at least it seemed to change not long
ago. There are also various pointers somewhere on the ccp14 site
(www.ccp14.ac.uk) under a heading like "gsas tips and tricks".

Many seem to manage. The gsasnews.txt file is what you seem to be
missing. Anyway - the ".mac" files are read by the expedt program via
an @r command. They just provide the keystrokes you would have given to
expedt had you typed things in manually.

Bob Von Dreele would be a good person to start by asking - he is very
helpful. Almost all of the functionality is available through the mouse
with expgui, as mentioned above. If you have a specific idea that would
make the program "more user friendly" then perhaps you'd like to
program that up and give it away for free?
Hopefully some of thise hints point you in the right direction?
