PROTEL (PRocedure Oriented Type Enforcing Language) is a propiatary language
developed by Bell Northern Research. It was developed in the 70's for 
development of the DMS-100 family of telephone switches. Currently, the
program for the DMS-100 is around 15 millions of code and the widely held
opinion is that PROTEL was/is crucial to this achivement. 

PROTEL is (very losely) a PASCAL derivative. We are now at version 5 of the
language and still making changes as we learn how to handle large S/W
project. We like to think we have a better language than Ada and Modular-n
before either was defined.

Some papers were published a decade ago. I don't recall where, but I can 
find the references if you want. (But I can tell you the published papers
are mostly obsolete.)

If there is interest, I can post a summary of the features and what makes
the language distinct (dare I say better?)


P.S. Bell Northern Reseach is the R&D sudsidary of Northern Telecom. We
     are competitors to AT&T Bell Labs.
