Ratbasic
As part of my volunteer work for Mount Madonna Center
in 1983-1984
I developed a pre-processor for CBASIC (from Digital Research, Inc).
It was called Ratbasic (Rational BASIC) and was modeled on Ratfor (Rational FORTRAN).
I wrote an extensive (40 page!) document for it (that took almost as long
to perfect as the software itself!), formed a teensy (and very temporary) company (Sahadev Software),
and tried to market the software with the help of a company in Ohio.
Here's the introduction to the document I wrote:
The software was described in a newsletter for CBASIC programmers:
Here are the two books that inspired the software:
CBASIC User Guide - Adam Osborne, Gordon Eubanks Jr., Martin McNiff. Published by McGraw Hill in 1981.
Software Tools - Brian Kernigan, P. J. Plauger - published by Addison-Wesley Professional in 1976.
On the back of the CBASIC book it says:
"The CBASIC language may be the most advanced version
of BASIC yet created. Like Pascal CBASIC requires no line
numbers and lends itself to highly organized,
structured programs - programs that are readable, modular,
and easier to change.
CBASIC is as easy to learn as BASIC.
It may be the only computer language you'll ever need to learn."
[[ 2016 - That last sentence is ridiculous - but it was 1984 – long
before the explosion of the internet and the proliferation
of the many many powerful, advanced, modern languages (like
Perl, Python, PHP, Ruby, Java, Javascript, etc., etc., ...). ]]
Finally, Ratbasic was not used very much at all and quickly became obsolete.
