The RAP FM header under MFS

When used by MFS, the reset attached process (RAP) FM header can be sent to IMS to delete the demand-paged output message in progress (prevent further processing).

This header is equivalent to the MFS operator control function of NEXTMSG. This header can also be sent to IMS to delete the operator logically paged message in progress. A RAP FM header cannot be followed by function management data. The RAP FM header is not sent by IMS.
