[Coco] NitrOS9 and Basic09

[Bill Pierce]

>From the looks of the code in runb, it was optimized as well. Of course, I know the 6309 version was optimized. And yes Curtis, your changes are there.

But still, with basic09's overhead, and the fact you need exact timing, I suggest C or (ultimately) asm for your project.
Basic09 is definately faster than BASIC, but much slower than C (which compiles to ML) or asm.

For the best of both worlds, you could create the timing critical sections as ML subs for the basic09 front-end.

There were a few cursory speed ups done to BASIC09 (I can’t remember if they
were ported to RUNB… I think I was going to finish BASIC09 first, and then port
it back to RUNB but never got that far). I don’t know if Boisy and co. took it
any further than that. There were some math speed ups, and some loop speedups,
from what I (faintly) remember.

looking forward to the great guys that built NitrOS9 to give Basic09 a work
over, I think.

work faster, so I can slow it down. Now I'm sure that doesn't make much sense
but, there are times when I would like it to be faster than it is. But other
times, I need it to slow down. I use this machine for operating my "Micro-Mill"
and when I'm just moving the head, it takes forever, using pokes to step the
stepper motors. However, when it's actually cutting metal, that would be too
fast and I would love to be able to slow it down. That's the easy part. Speeding
it up is not.
