Sounds good.  There are various ways to combine the source files, but they are all external to
SatPC32.  I have just gotten so used to using different groups that my fingers are already programmed
with that macro.  :)  

I like the description of groups as aliases!  I will steal that for future explanations.

<Hi Alan,
<Ok, so let me play this back.  First, I understand the source 
<files.  And I think I understand now that in a sense "groups" 
<are aliases for the source files.  I can set it up so that 
<"Diverse" is kind of the same as tle.new if I wish.  I'm 
<really not sure what good that is, but ok.  And I do 
<understand that "standard" is the default group when you start it up.
<And short of manually mixing source files, there is no way to 
<assign the lower right letters to satellites in different files.
<Do I mostly have that right?
<By the way, it appears that AO-73 has already moved out of 
<tle-new.txt but it moved into cubesat.txt, not amateur.txt.  
<That's why I wanted to select one from cubesat and others from 
<amateur.  Maybe it will move again.  Somehow 'cubesat' seems 
<like an odd grouping.  The other Celestrak groups are by 
<function or source (NOAA, amateur, etc) but cubesat is by 
<form.  Anyway...
<Thanks for all the help and 73,

<	<Hi Everyone,

<	<I've used SatPC32 for a number of years, but I have

<	<"simpleton" mode, it would seem.  Now that AO-73 is in the
<	<"cubesat.txt"

<	<next step in
<	<my education about this program.
<	<
<	<Here the current general question:  How do "groups" work.  I
<	<have googled,
<	<and the term seems to be used both for Celestrak groups and
<	<for the groups
<	<in SatPC32 (e.g. Diverse, Standard, etc).  I mean the SatPC32
<	<groups.  What
<	<I want to do is to have a number of satellites selectable with
<	<the A,B,C...
<	<buttons in the lower right.  But right now, I have to 
<pull down the
<	<satellites menu and select "cubesat.txt" to get AO-73 and
<	<"amateur.txt" to
<	<get, say, VO-52 and SO-50.  And whenever I switch to a new
<	<keps file, all
<	<the satellites I have selected as current for the previous
<	<file disappear
<	<from the right column.
<	<
<	<Somehow, I suspect that 'groups' are the answer to this, but I
<	<can never

<	<useful.  It
<	<looks like I can edit "standard", for example, so that if
<	<selected, it uses
<	<the satellites selected from amateur.txt or 
<cubesat.txt but not both.
<	<
<	<Ok, so when I get into a pickle like this, it is usually
<	<because I don't
<	<understand the concept or the model that the program is using.
<	< So rather
<	<than (or as well as) "click x, select y, edit xxx.txt" the
<	<kind of help I
<	<hope I can get would be include "how are groups supposed to be
<	<used?"  And
<	<by the way, I have read the manual, and it again seems
