Answer / sumit agnihotri
vsam file record are enter in a sorted order but when we
retrieve a records in KSDS so we specify a primary key
(unique) , in ESDS we enter a record in any order but
retrieve a records through the RBA (Relative byte address)
who r auto-generated, and also enter a record in any order
but retrieve records through the RRN (relative record
number)....
so the Answer is that we enter a records in a VSAM file
in a sorted order ....
