Btrieve Record Manager (ver 5.10a) Abandoned Freeware This Btrieve Record Manager is required to run a custom database that was built using the Btrieve transactional database design program. DOS Btrieve went up to version 5, and was a TSR (Terminate-and-Stay-Resident program) which functioned as an API (Application Programming Interface) database engine, supplying applications programs with function calls to implement a multi-user database with record locking. file = BTR510A.zip Note that although the Btrieve Record Manager needed to access a database is freeware, the DOS Btrieve transactional database design program is abandonware. Btrieve has been superceded by PervasiveSQL, but PervasiveSQL can only read records written in Btrieve 6.15 and higher. Use the runtime interpreter when you only need to -read- a database. However, so that you also have the ability to manipulate a pre-version 6.15 DOS database to extract the information fields, I am including the full two disk set of the Abandonware Novell DOS transactional database design program, version 5.10 (requires setup). file = Btrieve5.zip
