How to create a vsam file from a flat file?

STEP1:Sort the input flat file in an ascending sequence//step1 exec pgm=sort//sysout dd sysout=*//sysin dd * sort fields=(starting location of the key field,length in bytes,sort seq(asc or desc),format(ch))/*step2;create the VSAM cluster using idcams//step2 exec pgm=idcams//sysprint dd sysout=*//sysin dd *define cluster(name(your.base.cluster) -volumes(*) - keys(length in bytes,starting position of key field) - recordsize(avg,max) -freespace(20 ,20)) - data(name(your.base.data) -)index(name(your.base.index) -controlintervalsize(4096)))Step3:Use repro to load the flat file to vsam file//step3 exec pgm=idcams.//sysprint dd sysout =*//sysin dd *REPRO INDATASET("FLAT FILE") OUTDATASET("YOUR BASE CLUSTER FILE")//

Actually , the question asked how to create vsam file from a flat file,

 let me clear we can not create flat file to vsam dataset, only we can copy records of flat file to vsam dataset using repro command.

 the above example shows copy of flat file to vsam not conversion.

thanks

yes manoj is right.

No Jayakumar is right, that is the way of conversion of flat file to KSDS. First sort, then copy to KSDS.
