There has been a question concerning the commercial availability
of compilers.
The CCITT developed recommendations for what was marketed to be
a compiler for telecommunications industry, called CHILL (CCITT
High Level Language). It turned out to be similar to Pascal, and
not at all telecomms oriented (I'm not sure how a compiler like
that could be implemented).
The question is :-
Is there an application of this commercially available (thru a 3rd
party ?) that runs on the VAX.
ITT (now CIT-Alcatel) developed the CHILL ITT subset back in early
'80's, added support for IO and ASM functions, layered program-oriented
languages on top of the CHILL syntax (supporting relational database
access, inter-module data communication, data structure/mode access
from libraries etc), and used this to develop telecomms applications
(specifically system 1240). The tools have now been ported from
IBM to VAX environments for the development chain, with communication
to the IBM main-frame back end for the production chain.
Any leads ??
Thanx, Alex

Some years ago, I spent several months doing an investigation to
see what DEC should do about Chill. We spoke to a number of PTT
suppliers (particularly in Italy) and I went to a conference in
Denmark. Many of the PTT suppliers tried to persuade us to take
over their Chill (subset) implementations. At that time, nobody
had implemented full Chill. The reason for this was that Chill was
really three languages in one: some people preferred a PL/I like
structure, others Pascal and others Algol 68. The definition said
that the styles could not be mixed, and so everybody implented a
subset to conform to their idea of how the language should look.
There were a number of implementations on PDP-11 and VAX (with PDP-11
as target - compatibility mode for debugging). Unfortunately some
time ago I flushed my Chill file. However, the acknowledged experts
in this area are the Danish Datamatics Centre in Copenhagen, and
I am pretty sure they have implemented full Chill on VAX. They market
compilers under the name DDC International. I have just found their
address:
DDC International A/S
Lyngby
Copenhagen
Denmark.
There's some obscure postcode, but I don't have that.
