FABPMAIN DD statements

The DD statement requirements differ by the type of HD Pointer Checker processing (single-step job or multiple-step job), which is controlled by the TYPE keyword of the PROC statement.

If you want to run HD Pointer Checker in a single-step job, the parameter for the TYPE keyword is ALL.

If you want to run the SCAN process, the CHECK process, and the BLOCKMAP process of HD Pointer Checker individually, the parameter for the TYPE keyword is either SCAN, CHECK, or BLKMAP.

Recommendation:: It is strongly recommended that you use PROC TYPE=ALL and not PROC TYPE=SCAN and PROC TYPE=CHECK. By using PROC TYPE=ALL, the JCL statements will be simpler, the performance will improve, and the total size of the work data sets will be smaller.
Multiple jobs are not recommended because the specification of work data sets is complicated. If you must do so, however, refer to the examples in Example 4: (Standard database analysis) Multiple jobs.
