SUBSYS with DD Statements and SVC 99 Text Units

SUBSYS can be specified as a keyword on a DD statement and as a Text Unit (TU) on SVC 99. In call cases, the syntax is equivalent to:

SUBSYS=(subsystem-name[,subsystem-subparameter]...)

Where :

• subsystem-name is a 1-4 character subsystem name
• subsystem-subparameter is 0-254 parameter strings, each 0-67 characters in length and separated by commas

For example, on the DD statement:

//someddn DD SUBSYS=(OODA,A,DKP39CPM,’PPP3’,STD,,USER),
    //           DSN=MFIDSA.SUBSYS1B.NEW.OODA.NOTUSED,
    //           OUTPUT=(*.OUTSJ,*.OUTHORSE)

• subsystem-name is OODA
• subsystem-subparameter strings are A, DKP39CPM, PPP3, etc. These treated as if it were coded as single 30-character string OODA,A,DKP39CPM,PPP3,STD,,USER
