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).^[1]

Superplan introduced the keyword für as for loop, which had the following form (${\displaystyle a_{i))$ being an array item):

Für i=base(increment)limit: ${\displaystyle a_{i))$ + addend = ${\displaystyle a_{i))$
