chain-This file operation is used to randomly retrieve a
record from a file.The factor 1 value is mandatory for chain
operation. The factor 1 value must be key field or RRN.Chain
operation=setll+reade. In the case of chain it will points
to a particular record, not store the value in the input
buffer.it will not read duplicate records.if the value not
found the "hi" indicator will turn on.
Reade-Reads equal records from a file when we use setll or
setgt.Reade operation alone will not work.In the case of
Setll+reade, the record will be pointed and store the value
in the input buffer.Then read equal records from a file
sequentially. it will read all the duplicate records. The
factor 1 value is not mandatory for reade,if used,the key
value must be in factor1.
