In the following example, the direct-access spool volume defined by the ddname SPOOL1 is formatted and assigned membership in spool partition PART1. Cylinders 30 and 31 are allocated to the STT.

FORMAT,DDNAME=SPOOL1,STT=(30,31),SPART=PART1

The corresponding DD statement in the JES3 start procedure is:

//SPOOL1 DD DSN=JES3.QUES2,DISP=OLD,UNIT=SYSDA,       X
//          VOL=SER=MVSRW1
