[Coco] origins of OS-9

[Stephen H. Fischer]

If you compare Microware's BASIC09 and TSC's Basic / Preprocessor they both 
have a compiler type operation.

Other basic's like DECB either read the original source line or a tokenized 
form.

The industry was going away from basics like DECB requiring line numbers for 
all lines and only two character variable names.

Thanks Bill for his great basic used in the CoCo!

I just found a Microware ad in the Mar-Apr 1979 issue of 68 Micro
Journal (vol1 no2).

... the A/BASIC
compiler ...

..so it seems Microware had quite some experience with operating
systems and BASICs prior to the 6809.  Motorola's decision to partner
with them for the Basic09 and OS-9 projects may well have been based
on these products, and I do wonder if some of the ideas if not the
code of RT/68 are present in OS-9.
Interesting stuff.
