A.0 Appendix A. IMS Spool API Overall Design

The IMS Spool API is an expansion of the IMS application program interface that allows applications to interface directly to JES and create print data sets on the JES spool. These print data sets can then be made available to print managers and spool servers to serve the needs of the application.

This appendix describes the design of the Spool API and how an application program uses it. Considerations for coding an application program are included.
