The parameters are:vvvvvvvNAME specifies that the cluster’s name is EXAMPLE.RRDS1.RECORDSIZE specifies that the records are fixed-length, 100-byte records.Average and maximum record length must be equal for a fixed-length relativerecord data set, but not equal for a variable-length RRDS.VOLUMES specifies that the cluster is to reside on volume VSER01.TRACKS specifies that ten tracks are allocated for the cluster. When the clusteris extended, it is to be extended in increments of five tracks.NUMBERED specifies that the cluster’s data organization is to be relative record.TO specifies that the retention period is set to expire January 12, 2015. Note thatthe year (2015) is specified as a four-digit number and concatenated with theday (012). The retention period could also have been set by using the FORparameter, followed by the number of days the cluster is to be retained.CATALOG specifies that the cluster is to be defined in a user catalog, USERCAT.Define a Linear Data Set Cluster in a Catalog: Example 11In this example, a linear data set cluster is defined in a catalog.//DEFLDS JOB ...//STEP1 EXEC PGM=IDCAMS//SYSPRINT DD SYSOUT=A//SYSIN DD *DEFINE CLUSTER -(NAME(EXAMPLE.LDS01) -VOLUMES(VSER03) -TRACKS(20 10) -LINEAR -CATALOG(USERCAT)/*The DEFINE CLUSTER command builds a cluster entry and a data entry to definethe linear data set cluster EXAMPLE.LDS01.
