Hi Gayathri

A VSAM ESDS file is a sequential file and therefore does not have a mechanism for deleting or inserting records within that organization. Records can be updated in place, which is what allows for a programming solution, such as "logically" deleting or replacing a record within the file.

How 2 view a record in a KSDS file without knowing key?


the KSDS file should be processed sequentially....
the record key option is used only when we know the key and used ofr random processing

See the site to get more about Record Key
