> Others mentioned COBOL already and one can also look at Fortran libraries like in astronomy, etc... If you do that, you might as well mention Algol, as currently instantiated as C++, C, Java, C#, and so on. COBOL from 1965 isn't the same language a Cobol from 1995; ditto FORTRAN-IV vs Fortran 95. The only difference is that the names haven't changed as much compared to what the Algol family has gone through.
