Re: Procedure pointer use cases

I agree with Buck re callback routines. I have also made extensive use of them in other scenario including data base driven menuing systems.

You might find some ideas from this article http://ibmsystemsmag.com/ibmi/developer/rpg/how-flexible-are-your-calculations-/ <http://ibmsystemsmag.com/ibmi/developer/rpg/how-flexible-are-your-calculations-/> and the follow up http://ibmsystemsmag.com/ibmi/developer/rpg/even-more-flexible-calculations/ <http://ibmsystemsmag.com/ibmi/developer/rpg/even-more-flexible-calculations/>. These detail pointer based solutions to "RPG can't do that" type problems. Note that these solve "can't do" rather than "best solution" problems. Sometimes they are the best solution only because the alternative (massive If/Else or Select blocks) are too horrible to contemplate!

I've been doing RPG for 20 years, and I don't think I've ever said "this looks like a job for procedure pointers". I was wondering if anyone could share real-world examples where procedure pointers would be the best solution?

Thanks
