A language allegedly used by the Swedish Navy in the 1950s (which would make it even older than INTERCAL) and made known to the world through anonymous postings on alt.folklore.computers. Its character set consists only of digits and a few symbols, and its only data types are pointers and fixed-point numbers ranging from -1 to 1 exclusive. Early versions had a probabilistic jump instruction, which if given a negative probability would act as a COME FROM. Sadly, this feature was removed in later versions. Kvikkalkul has no comments, to prevent the risk of them being inconsistent with the code.
