It would go on your EXECIO command - that is the one getting the

You'd find that the overhead is MUCH less. Remember, you now have the
overhead of interpreted Rexx code, every time though the loop. A
Pipeline interprets its specification once, then runs the data though
it. As the amount of data increases, the overhead becomes less and
less..
