Linking Application Programs

All application programs using CA Datacom CICS Services must be link edited with one of the following modules to establish required communication:

Note: DBCSVPR and DBCSRPR use the exact same code. Except DBCSVPR runs with AMODE=24, RMODE=24, and NORENT, whereas DBCSRPR runs with AMODE=31, RMODE=31, and RENT. We recommend that all new programs you develop be link edited using DBCSRPR.

To access CA Datacom CICS Services, the application program must issue a standard call to the DBNTRY CA Datacom/DB entry point or to the DBSQLE entry point for SQL. Although the DATACOM entry point is still supported, we recommend using DBNTRY. The inclusion of DBCSVPR or DBCSRPR by the IBM Linkage Editor resolves the call to the entry point.

Note: Only command-level is supported with CA Datacom CICS Services r11 or higher. Therefore, the register 13 of the caller has to point to the 18 fullword Register Save Area before the call to DBNTRY.

Select one of the following options for including the DBCSVPR routine:
