PBO and PAI

530 Views

what is PBO and PAI in Dialog Progamming?

I know this definitions :

PBO (Process Before Output) – Before the screen is displayed, the PBO event is processed.

PAI (Process After Input) – When the user interacts with the screen, the PAI event is processed.

But I want clear meaning of this two.....Before screen means what and

when user interacts means what?
