lets assume it as a fixed length record, so it retrieves 95th record
VSAM relative file organization
(Also referred to as VSAM fixed-length or variable-length RRDS (relative-record data set) organization.) A VSAM relative-record data set (RRDS) contains records ordered by their relative key. The relative key is the relative record number that represents the location of the record relative to where the file begins. The relative record number identifies the fixed- or variable-length record.
In a VSAM fixed-length RRDS, records are placed in a series of fixed-length slots in storage. Each slot is associated with a relative record number. For example, in a fixed-length RRDS containing 10 slots, the first slot has a relative record number of 1, and the tenth slot has a relative record number of 10.
In a VSAM variable-length RRDS, the records are ordered according to their relative record number. Records are stored and retrieved according to the relative record number that you set.
Throughout this documentation, the term VSAM relative-record data set (or RRDS) is used to mean both relative-record data sets with fixed-length records and with variable-length records, unless they need to be differentiated.
