[comp.lang.c] Computer Language Translation

tkueny@nfsun.UUCP (Todd Kueny) (02/27/91)

Several years ago I founded a company called LEXEME which did
language translations from a variety of computer languages to
both C and Ada.  The company did okay but died for reasons unrelated
to the technology.  The technology was very effective.  For example:
There is an AN/UGC-144 terminal in Saudi Arabia running Ada which
we created.  We probably converted several million lines of code
over the course of 4 or 5 years; much is still in production.

Is this still a viable business area?  Are companies willing to
consider translation as a viable business alternative?

It seems that there is a lot of interest in Ada these days as well as
in translations.  It is interesting to note that there are a lot of
'translators' available which claim to convert FORTRAN and so forth to
C or Ada very easily.  These are often low in price.

I still believe that hard part of translation is not really the
conversion part, i.e., compiler-like technology can do everything
which is reasonably possible, but is instead the project planning and
execution.  The more difficult parts are moving the run-time, making
sure the Ada compiler does what you want, making sure task switches
happen fast, making sure that the source get frozen, knowing how to
test, etc.

I would like to hear any comments concerning translation that people
may have.  Only serious comments please, no flames about why its a
terrible thing to do; some of us have no choice.

The problem is not translating a bad design in FORTRAN into a bad
design in Ada--I'm sure that can be automated.

The question is--is there any way to automate the translation of
a bad design in FORTRAN into a good design in Ada? I doubt it.
