Answer / krishnan a
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))

On which dataset you can have alt index?
I have three fields in a Variable VSAM file X(2) Y(10) occurs X times Z(02) Say for the first record X=2 then the length of the file is 2+(10*3)+2=34 second record, x=4 then 4+(10*4)+2=46 If any time if the field x is updated then the total length changes. Is it feasible? Is it
