Operation: Obtain tuning and capacity planning information on the use of XCF signalling paths. Register 2 points to the area where XCF is to return member information. XCF is to store the return code and reason code into the variables RETURN and REASON. The code is as follows:

         LA    R2,MYAREA     LOAD ADDRESS OF DATA AREA

         IXCMG DATAAREA=(R2),DATALEN=AREALEN,TYPE=PATH,                X
               RETCODE=RETURN,RSNCODE=REASON,MF=S

MYAREA   DS    CL4096        AREA TO PLACE MEASUREMENT DATA
RETURN   DS    1F            RETURN CODE
REASON   DS    1F            REASON CODE
AREALEN  DC    F'4096'       LENGTH OF THE DATA AREA WHERE             X
                             MEASUREMENT INFORMATION IS PLACED
