Surprisingly, nobody's thrown my name out here yet...but "if you're
using a cursor you're probably doing something wrong" is definitely a
phrase I've thrown out here many times.

The point being SQL is designed for sets or records, but to many
people do things row by row since that what they are used to.

It's not just our platform, happens on other too. One of the MS SQL
Server guru's coined the term RBAR - Row By Agonizing Row....pherhaps
I'll steal it :)

Sometimes cursors are the right or the only way to do something...but
too often they are a poor choice.

In any event, like Scott, I'm confused as to what you're asking.
SQL-CLI doesn't really factor into the use or non-use of cursors.

What do you want to do?

I have seen it indicated in many posts in the past that if you are using cursors
in SQL, you are doing something wrong.
If I have only RPGLE and CL to work with and SQL-CLI is not an option, how would
I select multiple rows for a set of conditions and return them in an ordered
condition using embedded SQL with a CURSOR?
