The Reorg function of FPA operates in a virtual storage region as z/OS batch job steps. HFPMAIN0 runs in 31-bit addressing mode.
DD statements for the Reorg function
DD statements of the FPA Reorg function determine the input and output data sets and specify how to run the Reorg function.
Utility control statements for the Reorg function
The utility control statements for the Reorg function define the user description of the GLOBAL command, the REORG command, and the optional LOADCTL, REPORT, and THRESHOLD subcommands, all of which control the Reorg process.
