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.
Units 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.
