Beebe describing SFTRAN3 at Sloan history of programming languages
During the later 1970s and the 1980s, I was actively involved in
developing a large software package, PLOT79, based on the 1979
SIGGRAPH CORE Proposal. This code was largely written in SFTRAN3, a
very nice structured Fortran dialect developed at JPL/Pasadena, and
used at that time for part of the flight control software for some of
the JPL space probes.
I have a great fondness for SFTRAN3, since it made it possible to
write a large amount of highly-readable code, with a very low
incidence of bugs, that could be automatically translated to Fortran.
The PLOT79 source tree in my system has 178,807 lines of SFTRAN3 code
(counted as I wrote this letter).
Today, such a project would be done in C or C++, or perhaps Java, but
in the late 1970s, of these, only C existed, and it was then available
only on a very limited set of environments. Pascal was far too
restrictive and nonportable, and in any event, PLOT79 was intended to
be a support library for scientific software, which was largely
written in Fortran. Thus, the SFTRAN3 language is largely of
historical interest today.
One of the projects that I did with SFTRAN3 was to substantially
extend Brenda Baker's struct processor, which turned Fortran 66 code
into Ratfor, creating strsf3, which did much the same thing, but with
SFTRAN3 as the target language. SFTRAN3 is a much richer and cleaner
language than Ratfor.
Because this translation added structure, turning GOTOs into nice DO
WHILE, DO UNTIL, ... loops, it could usefully be employed to translate
a substantial body (> 100K lines) of legacy code to SFTRAN3.
