Ada Programming/Ada 83

83 __TOC__ Ada 83 is the first version of the Ada programming language. It was based in the so called Ada 80, a preliminary version of the language formally known as MIL-STD-1815 (published in December 1980). This standard was refined and standardized by the DoD and ANSI as ANSI/MIL-STD-1815A in February 1983 (note the additional 'A' at the end), which was later adopted by International Organization for Standardization as ISO/IEC 8652:1987.
