Converting SQLServer "select top..." statement to AS/400

All,

We are currently converting several SQLServer (7.0 and 2000) applications to
use the AS/400 as a database server. The front-end of these apps are and
will be .ASP files. Here is one problems we've hit so far. In SQLServer
there is the TOP option on a select statement. This allow a statement like:

select top 10 username, fullname, id from customer order by ytdsales

this statement would return a result set that contained only the top 10
customers ranked by year to date sales. When the program attempted to read
the 11th record it would receive an end of file condition. Simple, elegant,
nice! Now, there is no TOP operator on the AS/400. Suggestions?

1) Code to only read 10 rows and then quit
2) Code w/a subselect selecting by RRN in the superselect. 
3) Write results to temp file and select from there where RRN() <= 10
4) ?????

Please fill in #4.

Thanks,
-Walden
