Pascal was a strong-typed, structured language which had some popularity in the 1980s, although it lives on in various forms today (e.g. Delphi). The language was written by Niklaus Wirth in 1968-1969. It was originally designed for teaching purposes and was lacking in some areas, it was for example not possible to write a function which could receive variable length arrays or -strings as parameters. Thus a plethora of variant implementations of Pascal followed which all improved on the original Wirth design, however not necessarily in a compatible way.
program hello; begin writeln('hello world'); end.
