Hi… How can we use VSAM (KSDS, ESDS, RRDS) files in NATURAL module? Is it the same as Sequential file using WORK FILE?

Thanks

No, you need the&nbsp;&nbsp;&nbsp;[Natural for VSAM](http://techcommunity.softwareag.com/ecosystem/documentation/natural/nat427mf/dbms/nvs-over.htm)&nbsp;&nbsp;&nbsp;interface.

Thanks Wolf. I think the link you provided is for online mode. I need to write a Natural program for batch which will be reading many input work files. some of these work files will be sequential files and some files will be VSAM. Can I treat all files same?

Thanks

No. You still need the Natural for VSAM add-on to access VSAM files directly from Natural no matter if it’s in batch or under a TP monitor.
