7.3.2.2.1 Original Sysid Assignment Exit (cccSYSID)

The data element ORGSYSID is used by CA MICS to identify the
originating system of the data.  The cccSYSID exit is used
for specialized assignment of the ORGSYSID over and above the
ORGSYSID statement.  As an example, many data sources contain
ORGSYSIDs up to 256 characters.  Since CA MICS requires a
four-byte ORGSYSID, this exit can be used by the installation
to recode extra-long ORGSYSIDs to four bytes.  Another use of
cccSYSID is to assign an ORGSYSID when the input data does
not provide one.

cccSYSID is located in prefix.MICS.PARMS and is automatically
copied as part of the installation of the FDA.
