.file extension IO - Modula-3 object file
File extension IO description:
In Computer science, Modula-3 is a programming language conceived as a successor to an upgraded version of Modula-2. While it has been influential in research circles (influencing the designs of languages such as Java, C#, and Python) it has not been adopted widely in industry. It was designed by Luca Cardelli, Jim Donahue, Mick Jordan, Bill Kalsow and Greg Nelson at the Digital Equipment Corporation (DEC) Systems Research Center (SRC) and Olivetti in the late 1980s. Its design was heavily influenced by work on the Modula-2+ language in use at SRC at the time, which was the language in which the operating system for the DEC Firefly multiprocessor VAX workstation was written. As the revised Modula-3 Report states, the language was also influenced by other languages such as Mesa, Cedar, Object Pascal, Oberon and Euclid.
