Screenwrite <language> 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}.
