How do I keep the console open after the data is displayed? I assume I can use something like getchar(c) which (I hope) will wait for input from the keyboard. But what I really need to know is: What is causing the console to close (or how can I control when it closes)?
From a little experimenting, I think I may have discovered the answer tothis question. It appears that the console stops and waits for a keypress when you close it.
The reason your program doesn't stop and wait is that you're not closing it, and it thinks that there might still be more data coming.
Remember, the console isn't part of your program. You don't have an F-spec for it, and you don't use RPG opcodes to manipulate it. It's actually somethign that's opened in a service program in the ILE C runtime library.
When your program is activated, the ILE C service program is also activated. When you call printf(), it opens the console window and displays the output. However, you never do anything to end that service program or close it's console window. So, when your program ends, it returns control to the command line (or menu or whatever) and THAT program redraws the screen with it's own data, so the console seems to "disappear".
The solution, of course, is to end the service program that opened the console. And how you do you end a service program? By reclaiming the activation group that it's running in.
In other words, try running your RPG program (the one that calls printf) with ACTGRP(*NEW)
Whew. I'm out of breath now.
