Thanks to everyone...I've gotten a lot of help from many people, including
Erich Eichmann the author.  I thought it would be nice close of this thread
with the model I now have in my head, confirmed by Erich.

Here is what I think I really missed:  There is *always* a SatPC32 group
active, and it is the group that defines which satellites are chosen for
display in the ABC buttons.  You could have multiple SatPC32 groups
associated with the same data file, but each with different satellites
chosen, if that is what you wanted.  Then you select a different group to
get the different configuration.  But (the key to me) is that you can not
use a group to chose satellites from multiple different data files at the
same time.  And you don't really chose a data file for display without it
being associated with a group.

Erich also pointed out to me that there are 4 different configurations
(chosen by setup) which essentially multiply by 4 the number of different
groups that are available.

Thanks again to everyone.  And in case anyone missed it, AO-73 (named DNEPR
OBJECT AE - As in 'the AE35 unit') is now in Celestrak's amateur.txt and
also in 'nasa.all' which SatPC32 sources from AMSAT.

("HAL <http://www.imdb.com/name/nm0706937/?ref_=tt_trv_qu>: I've just
picked up a fault in the AE35 unit. It's going to go 100% failure in 72
