PC SORT is a computer program developed by IBM in the 1970s. It was designed to SORT data records in a database, allowing users to quickly and easily organize large amounts of information. The term PC SORT is an acronym for 'Program Controlled SORT'. The USER of the program is responsible for providing the instructions for sorting the data, such as the order of the fields, the type of sorting, and the output format. The program then takes care of the rest.
