Murali -

I think you need to take a class or buy a book about AS/400
programming in
RPG.  It also appears to me that you have a lot to learn about
subfile
programming and databases.  There are some very good books
available at
reasonable prices.  Go look in the midrange.com online book
store:
http://store.midrange.com/books.htm .

I don't mind helping you, but I expect YOU to have a basic level
of
understanding about some things.  I also expect you to help
yourself
whenever possible.  Most of the time I use the midrange forum
AFTER I have
exhausted all other avenues.

I would suggest that you start searching for the answers to some
of these
questions BEFORE you ask them:

1) on IBM's web site (http://as400bks.rochester.ibm.com),
2) in the FAQs here on midrange
(http://faq.midrange.com/data/cache/1.html)
3) or in the forum archives here on midrange
