Unique Wang COBOL Dialect Ported To Unix
Wang dialects of COBOL-74 and COBOL-85 have important places in the evolution of COBOL. Wang was among the first, if not the first, to integrate COBOL into environments built from the ground up to be interactive as well as batch. Wang also had a principal role in the COBOL standards bodies until the early 1990s. Wang extensions to COBOL involving record locking scope, rollback and rollforward recovery implemented at the file system level allowing transaction processing, and full interactive workstation screen I/O have often made it difficult to port Wang COBOL applications to other systems.
