         A columnar format {third generation programming
        language} similar in layout to {assembler} and used for
        {transaction processing}, solely on the {Honeywell} {Bull}
        {TPS6} {database}/transaction management system on their Level
        6 {DPS6} {minicomputers} running under the {GCOS6} {operating
        system}.  In the UK it was mainly used by local authorities
        and the Ministry of Defense.  Being proprietary technology,
        its popularity waned with the introduction of {open systems}
        standards, {relational databases} and {fourth generation
        languages} but it is believed that some systems made it
        through {Y2K}.
