Re: Procedure pointer use cases

For callbacks, mainly.

HTTPAPI and FTPAPI use them extensively.

I use them any time I have some part of the logic that I want to be flexible (the caller inserts his/her own routine to do part of the processing, and each callers logic might be different.)

This type of coding is ubiquitous in javaScript, so if you're used to that paradigm, it's easy to think that way when writing RPG, too.

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
