Abstract
Hash-coding storage arrangements are known which are capable of storing data values efficiently and permitting rapid testing of whether a given data value is stored. However, such arrangements may produce erroneous outputs. The invention reduces or eliminates these erroneous outputs by providing a further store (which may itself be a hash-coding storage arrangement) which identifies the erroneous outputs, and is used to suppress them.
