Ada Programming/Ada 80
< Ada ProgrammingComputing » Computer Science » Computer Programming » Ada Programming
Ada 80 was a preliminary version of the Ada programming language. The Military Standard reference manual was approved on December 10, 1980 (Ada Lovelace's birthday), and given the number MIL-STD-1815 in honor of Ada Lovelace's birth year.
The Ada 83 standard, MIL-STD-1815A, was later derived from Ada 80.
Ada 80 is just interesting from a historic point of view, there is no code that must conform with this standard.
