Superplan

 ( Programming Languages Created In 1949 ) 

Superplan was a high-level programming language developed between 1949 and 1951 by Heinz Rutishauser, the name being a reference to "Rechenplan" (i.e. computation plan), in Konrad Zuse's terminology designating a single Plankalkül program.

The language was described in Rutishauser's 1951 publication Über automatische Rechenplanfertigung bei programmgesteuerten Rechenmaschinen (i.e. Automatically created Computation Plans for Program-Controlled Computing Machines).

Superplan introduced the keyword as for loop, which had the following form ($a\_i$ being an array item):

'''Für''' i=''base''(''increment'')''limit'': $a\_i$ + ''addend'' = $a\_i$
