RE: FW: Niftiest thing(s) you have done in RPG ILE or /FREE

I'm not starting that holy war again, but here is an example.

Take a couple of tables that are of a Parent/Child relationship. Large tables, say, a million records for the parent, and 3 million for the child. These tables have their primary keys defined. Now write a program that reads in a do loop, running another do loop for the read of the child file in order to print some sort of report. Run the program and see how long it takes.

Now, if you can, write a matching record program to print the same report.

The Cycle/MR will outperform the Full Procedural program by orders of magnatude. I've done this numerous times when a accosted by an RPG newbie because he doesn't understand cycle programming.

You don't have to use Import in Java either. You subclass using the entire package. But you don't do you?

I'm done....

Why? What can I do in the cycle that I can't do without the cycle? How
does the cycle make the code more efficient? How does the cycle make
the code clearer to most folks? What's the advantage of using the
cycle?

And I'm not trolling...I've written (conservatively) a million
programs using the cycle back in the day.

That's total bunk, brother. Sometime the cycle is the best tool for the job.
