Fortran
     
         (Formula Translation) The first and, for a long
        time, the most widely used programming language for numerical
        and scientific applications.  The original versions lacked
        {recursive} procedures and {block structure} and had a
        line-oriented {syntax} in which certain columns had special
        significance.
     
        There have been a great many versions.
     
        The name is often written "FORTRAN", harking back to the days
        before computers were taught about lower case, but {ANSI}
        decreed, in about 1985 via the ANSI {FORTRAN} Technical
        Committee {TC}, that it should be "Fortran".
     
        See also: {Fortrash}.
     
        [Was {Fortran I} the first version?]
