Compatibility of application programs

Reassembling

Reassembling your application program by use of the product-sensitive macros is required only for programs or user exit routines that refer to either the HTCB or the HDMB control block.

Relink

Basically, no relink is required for running the application programs written for PO HSSR on IMS High Performance Unload.

Relinking with the language interface module (ASMHSSR, CBLHSSR, or PLIHSSR) is required only if you want to run an application under the IMS DL/I batch region controller (DFSRRC00). This is not recommended, but PO HSSR supports it. Include the corresponding language interface module (ASMHSSR, CBLHSSR, or PLIHSSR) from IMS High Performance Unload's HPS.SHPSLMD0 library, and link-edit it with the application program; otherwise an unexpected result, such as a system abend, might occur.
