Well, back in the 1980's up to early 90's, Modula-2 enjoyed a mild success in Europe.
replyGiven that it was available in 1978, and the satellites launched in 1982, it seems a plausible choice like any other, given the computing ecosystem at the time.
In 1999 I used Modula-2 for my first computer science/programming languages exam at university. The environment was a bit like Turbo Pascal 3.0, though with a more complete language (TP3 had no modules/units) and library, comparable perhaps to TP5.
replyUnits were introduced in Turbo Pascal 4, then TP 5.5 added OOP based on Apple's Object Pascal, further improvements were then based on the Object Pasca / C++ relationship on Borland's compilers.
