SQL and CLLE

I guessed at which forum upon which to post - if this is not correct, please
let me know and I shall repost.

I know we can use RUNSQL within a CLLE to execute, typically, an Insert or
Delete or such. But I would like to receive a value back from my SQL.

Here is what I wish to execute: Select row_length from qsys2.systables
where table_schema = 'A' and table_name = 'B'.

I want to use the value returned from row_length inside my CLLE program.
Just like we can do inside of SQLRPGLE.

Is this possible to do? I find no examples, anywhere, of how to return a
value from an SQL within CLLE.

As always, thank you all for your time.
