2.3 SMF Requirements

VCC writes variable length records to either a physical
sequential file or to SMF.  If DFHSM is implemented and the
VCC-DFHSM data collection interface is selected, the
VCC-DFHSM interface will likewise write variable length
records to either a (different) sequential file or as a
(different) SMF record.

Finally, for both standard VCC records and VCC-DFHSM records
written to their respective output data sets, a hybrid
approach can be effected by copying (DISP=MOD) or
concatenating these data sets into the dumped SMF data set.

If direct recording to SMF is chosen:

    o  User record numbers must be between 128 and 255.

    o  SYS1.PARMLIB(SMFPRMxx) must allow the user record to
       be written.

    o  SMF recording of VCC data is independent of SMF
       recording of VCC-DFHSM data.

    o  If both types of data are being logged to SMF, the
       record numbers specified must be different.
