Referbacks:

DSN,DCB,Volume are possible Referbacks

When the value of a parameter will be determined after the creation of the dataset,you can tell the system to referback to an earlier parameter and use the same value.

//DD1         DD    DSN=value,DCB=*.ddname

          (Mostly input and output dataset will have same attributes.)

//DD1         DD    DSN=*.dsname

UNIT parameter must be coded with VOL=SER

//DD1         DD    DSN=MUTHU.SAT,DISP=SHR,UNIT=TAPE,

VOL=SER=*.INPUT

  

A referback to DCB    

//DD1         DD    DSN=value,DCB=*.ddname

A referback to DSN     

//DD1         DD    DSN=*.DD0

Place a DD statement on the same volume as another datasetname     

//DD1         DD    DSN=val,                                                                                                   VOL=REF=*.ddname

Place a DD statement on the same volume as another dataset name

//DD1         DD    DSN=val,VOL=REF=dsname

A referback to a DCB in another job step

//DD1         DD    DSN=value,

//                 DCB=*.stepname.ddname

A referback to a DSN in a instream procedure

//DD1         DD    DSN=*.stepname.procstepname.ddname
