Summary: Thanks and ...


     Thanks Mike.  I had read your earlier posting, but mainly for the
the windowing info.  As such, I stuck it onto the stack and all I know is
"it's on file there somewhere".  Besides which, I felt that after a while
you might have more info (always a good excuse when I'm being lazy :-).

     Anyway, I'm writing a graphics program with what spare time I have.
I'm not sure what I'm going to do with it when I'm done.  I've considered
a few things, but currently it boils down to this:

     I'm writing a program which is sort of based on Jim Kent's "Flicker"
animation program for the Atari ST.  Jim's an old CoCo author (he wrote
the Micro Illustrator for the Color Computer--don't blame him for the
poor joystick interface because that wasn't his fault).  Jim allowed me
to copy his user interface.  Just recently however, I think Jim's gotten
interested in porting "Flicker" to the CoCo3 under OS-9.  I sent him
a note when I realized how *easy* it would be to do the animation parts.
Now, I'm going to write my program anyway, but if Jim comes out with
"Flicker" then it'll be the better program, so there won't be any point
in my doing anything until he decides whether he'd want to do anything
with "Flicker".

     As for C v. BASIC09, it's interesting.  I'm starting to think that
for this program C won't give any noticable advantage.  The graphics routines
in 'gfx2' are fine.  There are a few things that could be added, but then
you can always add another machine language file to call from BASIC09.
Mainly what BASIC09 will be doing will be following the mouse (one way or
the other).  Also, the way I program in BASIC09, it might be easier to
translate it to Assembler than to C.  In fact, I could try Pascal.  I
have the compiler but haven't used it since I switched to Level II.

     Now that I think about it, the main reason I didn't even start in C
was the fact that my C compiler is still not working pending a patch
to redirect the compiler from looking to /d1 for libraries and defs.
I still haven't found the patch to make that change.

Cheers! -- Jim O.
