DDNAME

The DD card name

DSN

The dataset referred to by the card

DISP

The specified dataset disposition. The valid values are:

• For DISP field 1 one of the following: NEW, MOD, OLD, SHR
• For DISP field 2 one of the following: DELETE, KEEP, CATLG, UNCATLG
• For DISP field 3 one of the following: DELETE, KEEP, CATLG, UNCATLG

UNIT

The specified UNIT

VOL

The specified Volume Serial.

There are four VOLSERS for each ON statement and the relation between these VOLSERS is OR logic, so that if at least one of the volsers satisfy the criteria, the DO statement will be activated.

If you use N (Not) at the END of the ON statement, it affects the next four VOLSERS.

SMS CLASS

One of the following classes:

• DATA
• STORAGE
• MANAGEMENT

O/N

Conjunctional subparameter that permits linking of ON statements. Valid values are:

• O (Or) - Only one statement need be satisfied.
• N (Not) - The condition in the following statement need not be satisfied.

%%$DDNAME

DD card DDNAME - Data definition name

%%$DDDSN

Dataset name

Note: A temporary dataset, starting with a prefix of &&* and followed by a number, is used when the DSN keyword does not exist in the JCL DD statement.

In this case, the %%$DDDSN variable shows this temporary value.

Example:

               _{4 //NDSNDEV  DD   DISP=(NEW,PASS),}                              

                  _{//         DCB=(LRECL=0080,BLKSIZE=3120,RECFM=FB,DSORG=PS),}   

                  _{//         SPACE=(TRK,(0001,0001),RLSE),}                      

                  _{//         MGMTCLAS=TOTO}                                      

_{CTJDSIW         4 WARNING: SPECIFIED MGMTCLAS TOTO does not exist. DSN=&&*00000001}
