This is because there are few reasons for people to build them. There
isn't a huge amount of it around, and most of it is in maintenance
mode rather than active development. My guess is that you already
know this.


> Question: If you have a language and grammar for JOVIAL,


We have a full front end for JOVIAL, based on our DMS Software
Reengineering Toolkit. See

Well, er, yes, under a commercial relationship. Building a robust
version of this wasn't easy or cheap.

We built our front end as part of a JOVIAL to (GNU) C translator,
which we also offer. No need for you to build one of your own :-} See
http://www.semdesigns.com/Products/MigrationTools/JOVIAL2C.html The
last software package we applied it to was mission software for a
rather advanced aircraft; it translated 350,000 lines of code
automatically into running C. You don't have to do a lot of
inspection.
