Answer / sundar selvaraj
- Read is a sequential operation whereas FIND is a random
search.
- Read returns records in the order of descriptor whereas
FIND returns records records in the ISN order
- Though both READ & FIND intiate a processing loop, READ
command returns only *COUNTER and *ISN. FIND returns
*NUMBER, *COUNTER AND *ISN
- Dynamic change of read direction is possible with READ.
This is not possible with FIND.
- Read is considered efficient for a large number of
records. FIND is efficient for a smaller number of records.
