If XCF is checking for status update missing, the routine checks the member's work queue:

• If the work queue is empty, the routine sets a return code of SEUPDRES to indicate the member is operating normally.
• If the work queue is not empty, the routine sets a return code of SEUPDMIS, and places user data (UDATACD) in register 0 to be passed to the group user routines of the other active members of the group.
