Screenwrite
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.
