Plankalkül (plan calculus) is a
computer language developed for engineering purposes by
Konrad Zuse between
1942 and
1946. It has a very good claim to be the first
high level language to be designed for a computer. It included assignment statements, sub routines, conditional statements, iteration, floating point arithmetic, arrays, hierarchical record structures, assertions, exception handling and other advanced features such as goal-directed execution. It was first published in
1972 and the first compiler for it was implemented in
2000 by the
University of Berlin.
