An improvement over VisiCalc (though using much the same command structure using the slash key), SuperCalc was one of the first spreadsheet programs capable of iteratively solving (cells that depend on each other's results). It would be over 10 years after the introduction of SuperCalc before this feature was implemented in, although in, manual programming of iterative logic could also be used to solve this issue. According to the SuperCalc product manager, iterative calculations were added when Sorcim changed from to binary math.
Since the precision of the two math packages was different, some IF statements resolved differently, and iterative calculations helped solve this problem. Versions of SuperCalc were later released for the, for running MS-DOS, and, after Sorcim was bought by (CA) in the mid-1980s, for (under the name CA-SuperCalc). The MS-DOS versions were more popular with many users than the market-leading Lotus 1-2-3, because it was distributed without copy protection, as well as being priced lower. By the release of version 3 in March 1987, a million users were claimed. New versions were published into the early '90s, after which Microsoft Excel dominated the spreadsheet market.
