A member places itself in the not-defined state. XCF is to place the value X'11' in the user state field and store the return code and reason code into the variables RETURN and REASON. The code is as follows:

          IXCLEAVE MEMTOKEN=TOKEN1,USTATE=STATE,USLEN=LEN,             X
                RETCODE=RETURN,RSNCODE=REASON,MF=S

TOKEN1   DS    CL8                      TOKEN OF MEMBER TO BE PLACED   X
                                        IN NOT-DEFINED STATE
RETURN   DS    1F                       RETURN CODE
REASON   DS    1F                       REASON CODE
STATE    DC    X'11'                    USER STATE VALUE
LEN      DC    F'1'                     LENGTH OF USER STATE DATA
