  A Programming Language
       
           (APL) A language designed originally by Ken Iverson
          at Harvard University in 1957-1960 as a notation for the
          concise expression of mathematical algorithms.  It went
          unnamed (or just called Iverson's Language) and
          unimplemented for many years.  Finally a subset, APL\360, was
          implemented in 1964.
       
          APL is an interactive array-oriented language and
          programming environment with many innovative features.  It was
          originally written using a non-standard character set but
          now can use ISO8485.  It is dynamically typed with
          dynamic scope.  APL introduced several functional forms but
          is not purely functional.
       
          Dyadic Systems APL/W is one of the languages that will be
          available under Microsoft's .NET initative.

          Dijkstra said that APL was a language designed to perfection
          - in the wrong direction.
