Modula-2

Structured procedural language introduced by Niklaus Wirth in 1979, based on his earlier Pascal language but adds modular and incremental compilation, and a number of "programming in the large" features.

Modula 2 was hugely influential in the field of informatics and at the least 50 other languages have been based on it in addition to having a direct or indirect influence on languages like Java, C# and Object Pascal, amongst the more notable languages that have been based on M2 are Modula 3, Parallaxis, Yafl, Oberon, Oberon-2, IEC61131, Umbriel, Component Pascal and Zonnon.
