Using IDCAMS Utility we can create the VSAM data Set.
//jobname JOB CLASS=P,MSGCLASS=P,USER=SYSADM
//STEP1 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SYSIN DD *
DEFINE CLUSTER(NAME(SAMPLE.datasetname)-
FOR(365)-
RECORDSIZE(64,64)-
CONTROLINTERVALSIZE(1024)-
TRK(10,5)-
NOERASE-
FREESPACE(30,30)-
INDEXED-
KEYS(64,0)-
SHARE OPTION(1 3))
