CHILL
From Wikipedia, the free encyclopedia
In computing, CHILL, (an acronym for CCITT High Level Language), is a procedural programming language designed for use in telecommunications switches (i.e., the hardware used inside telephone exchanges).
The language is similar in size and complexity to the Ada language. The first specification of the language was published in 1980, a few years before Ada. The language is unusual in that it supports two forms of declaration syntax, one based on Cobol and the other on PL/1.
There exists a CHILL compiler, provided by ITU (which is responsible for the CHILL standard, known as ITU-T Rec. Z.200; ISO/IEC 9496:2003 is the equivalent ISO standard and the text of the two documents is the same). In late 1999 C.C.I.T.T. stopped maintaining the Chill standard. The language is still used for legacy systems in some telecommunication companies.
A free CHILL compiler was bundled with gcc up to version 2.95, but was later removed. An object-oriented version, called Object CHILL, had been developed [1].
