The z/OS® version of IOCP runs as a job under control of z/OS. Run the z/OS
version of IOCP by using z/OS JCL statements. By coding
options in the PARM parameter of the EXEC statement, you can request the following IOCP functions:
Generate an IOCDS.
IOCP reads, validates, and checks the syntax of the input
statements. It generates an IOCDS based on the configuration defined in the statements. It produces
reports of the IOCDS generated, and, when requested, IOCP writes the generated IOCDS to the Support
Element hard disk.
Produce configuration reports.
IOCP reads one or more IOCDSs into storage from the Support
Element hard disk and prints the IOCP configuration reports. (See IOCP configuration reports for examples.)
See Running the z/OS version of IOCP for
a full description of the z/OS version
of IOCP. Figure 1 shows
an overview of the processing the z/OS version
of IOCP performs.

The card-image input contains IOCP statements.
IOCP processes the IOCP statements, generates an IOCDS, produces
reports, and (when requested) writes the generated IOCDS to the Support
Element hard disk.
The configuration reports allow you to check the I/O configuration
as defined in the IOCDSs.
The IOCDSs reside on the Support Element hard disk. At power-on
reset, the I/O configuration data is loaded into the hardware system
area (HSA). (Afterward, the I/O subsystem uses the data to control
I/O requests.)
