The resource manager parameter list (RMPL) is the interface between MVS™ and the installation-written resource manager. The RMPL tells the resource manager why it was invoked and provides information for its use during processing. RMPL fields indicate, for example, whether the resource manager is being invoked during task termination or address space termination, and whether the termination is normal or abnormal.
To access the contents of the RMPL, the resource manager must include the IHARMPL mapping macro, which provides the field names and describes their content and use. Detailed information on the name, offset, and meaning of each field in the RMPL appears in z/OS MVS Data Areas in the z/OS Internet library.
