Answer Posted / ipsita
A record address file contains either key-field limits or
relative record
numbers of records in a DISK file. By providing these
key-field limits or relative record numbers to the program,
a record
address file tells the program the records to read from the
DISK file and
the order in which to read them. A program can use no more
than one
record address file. Record address files must be further
defined on
extension specifications.
A record address file must be an input file. If it contains
key-field
limits, it must use the DISK or CONSOLE device and can be
used only with
indexed files. If it contains relative record numbers, it
must use only
the DISK device and can be used with sequential, direct, or
indexed files.
Record address files that contain relative record numbers
are called
addrout (address output) files, and they are produced by a
sort program
