Rajiniganth, if you define an externally-described data structure using
your
file, then all the fields in your file will be in that data structure at
the
same positions you determined from DSPOBJD.  After a read, you can then
substring
the data structure using the buffer positions you obtained using DSPOBJD.

If you are using a program-described file, then just code a data structure
in
the result field of your READ operation, and substring that data structure.
