I've got it.  Not too bad (though my version has a bug in
setting graphics modes).  However, I find I don't use it much.
Most things for which I want quick development, I just do in BASIC.
Two reasons:
   1. Compile time.  I write something, start compiling, and take a nap.
      Later (much later) I then have to link it all.  Take another nap.
      Oops.  I really want the output to look like this.  Take two
      more naps.  What if I change that?  Take two more naps.
   2. Run speed.  When I ran a program, it didn't seem all that fast,
      so I tried running
      10 look at atari built in clock
      20 FOR I=1 TO 1000
      30 FOR j=1 TO 1000
      40 NEXT J
      50 NEXT I
      60 look at atari clock again
      70 print difference
      80 END
      and a C equivalent.  Deep Blue C was faster by a factor of 3.
      Somehow, I thought a compiled vs interpreter should do better than that.
Anyways, C usually isn't worth the trouble.  If I'm going to the trouble,
I'd just as soon do it in assembly, and make it *fast*.

What I've heard about Deep Blue C is that it compiles to an interpretive
code ( a P code if you will), and thus it is slow.  Unfortunately, I've
also heard it is a more standard version than the other alternative(s).

Personally, I use Forth, as its fast and interactive.  I rarely have
to recompile the whole thing when I make mods (no time for a nap),
as Forth is an incremental compiler (you can interactively compile
small bits at a time).
