Wendy,
Thanks for getting the combo_doc started.
I began editing it a bit, see the above version.
I also made comments in the text on some semantics.
You'll see how far I got.

But, as I told you, it's easier to edit an existing
document than to start over and write it afresh.

I would like it to be less wordy/chatty. But not by much,
or it becomes as unreadable as other documentation.

I wonder if we shouldn't have a synopsis like documentation
at the top (rather than all those big empty blue headers)
with links to chattier explanations below the top level.

If we explain the illiGadget conventions, then the
synopsis can be quite short.

George

Well, I really didn't make much headway.  I did Curves C, D, and I from
scratch (using the same 32 point format you have been using), but C and D
don't really count, do they :o)?  And I know you already have I in
foo.sps, but I really wanted to see if I could do it from scratch.  I did
go ahead and make four copies of each and edited the levels, so we can see
each one in combo, though, so if you want to look at them, here they are:

If you let me know that this is what you want, I guess I'll start on the
ugly ones tomorrow.

I have a question about the hair that designates the outside of the
curve...how can we tell on our curves?  Can we color the inside one color
and the outside another, or should I be able to tell from the way I moved
the curve? (It's still not second nature to me, yet.)

Not yet. That will come later. There is a way to do it, but it requires
hacking combo.

>and the outside another, or should I be able to tell from the way I moved

Probably not.

>the curve? (It's still not second nature to me, yet.)

Thanks for coming to supper, hope your son is OK.

I still need to do some formatting (bolds and italics), but this is the
basic idea:

I added some images to the latest combodoc.html.  I haven't resized them,
yet, but I wanted you to look at them and see if you want to use them, or
not.

Is this the H1 curve?  I think I got it right, but I want to make sure
before I use it as a template to go on to the next level.

Let me know if I e-mail you too much.  I just do it so I don't forget
and maybe you can get back to me and I can get something else done
before the next time I see you.  I can just as easily e-mail them to
myself and then ask all of the questions the next day.

I guess it would help if I tell you how to find it.

I don't understand curve G bar from line 24.  it looks like only one curve.

From whubbard@uiuc.edu  Thu Jul  4 00:49:58 2002

Forget the link I sent you earlier. It's probably invalid by now.  All the
curves that I have done so far are here:

http://archive.ncsa.uiuc.edu/Classes/MATH198/whubbard/public/philever/

The ones that are 4K are the ones that have 4 copies of that curve, the
others are ones that I used to make the transition from one curve to the other.

From whubbard@uiuc.edu  Fri Jul  5 16:45:08 2002

I'm still a little confused about HOW the f1 curve becomes the g curve and
the g curve becomes the h1 curve.  I'm assuming that is the saddle point in
combo?  How do the two curves become one at that point?  I got as close as
I could to the g curve, but it is still two curves.  That's the only way I
could see to do it.  It's in the philever directory.

Wendy,
I finally got to looking at the f1-g-h1 curves. (These look very good,
it's something we can work with.)

But you're question is a good one, I haven't gotten that far yet.
Tell me about your labelling scheme (I don't want it changed, I just
want to know what you're using.)

 >>Tell me about your labelling scheme

I'm going by the chart you made.

Once I get the curve drawn, I save that as the intermediate for the next
one (i.e. ctodbar.sps is really only one copy of c that I will use to make
dbar).

Then I take that one and make four copies of it and change the name to the
name of the curve that it will represent when we put them all together
(ctodbar.sps becomes c.sps).

I'm in the process of putting together the surface on the far right of the
chart right now, but I don't know what to do about the g curves, so I guess
I'll leave them out for now and see what combo comes up with.  It should be
interesting.
