Using reference pattern services z/OS MVS Programming: Callable Services for High-Level Languages SA23-1377-02 |

The two reference pattern services are CSRIRP and CSRRRP. First, you issue CALL CSRIRP to define a reference pattern for an area; then, issue CALL CSRRRP to remove the definition of reference pattern for the area. To avoid unnecessary processing, issue the calls outside of the loops that control processing of the data elements contained in the area. |
