Incomputing,CHILL(an acronym forCCITTHigh Level Language) is aproceduralprogramming languagedesigned for use intelecommunicationswitches (the hardware used inside telephone exchanges). The language is still used forlegacy systemsin some telecommunication companies and forsignal boxprogramming.
The CHILL language is similar in size and complexity to the originalAdalanguage. The first specification of the CHILL language was published in 1980, a few years before Ada.
ITUprovides a standard CHILL compiler. A free CHILL compiler was bundled withGCCup to version 2.95, however, was removed from later versions. Anobject-orientedversion, called Object CHILL, was developed also.[1]
ITUis responsible for the CHILL standard, known as ITU-T Rec. Z.200. The equivalentISOstandard is ISO/IEC 9496:2003. (The text of the two documents is the same). In late 1999 CCITT stopped maintaining the CHILL standard.
CHILL was used in systems of Alcatel System 12 and SiemensEWSD,for example.
