ABSTRACT

An auxiliary processor (AP) for interfacing ORACLE SQL with APL2/PC, modeled after APL2/370's AP 127 auxiliary processor, is described. While providing direct compatibility with AP 127 service requests, the AP described here also offers several enhancements to AP 127 service requests. Although written for ORACLE SQL and 16-bit APL2/PC, the programming style employed provides a great deal of isolation between the database management system (DBMS) and target interpreter, thus providing a high degree of portability to both other DBMS implementations (e.g., Database Manager under OS/2) and target interpreters. Besides providing SQL services for a desktop APL environment, the AP demonstrates that it is possible to write large auxiliary processors for APL2/PC using a high level language, and that the resultant AP can be installed in extended memory and run in protected 80x86 CPU execution mode.
