It's been a long time since my last '400 related post. But then, it's been a long while since I touched a '400, so that's hardly surprising.

Still, this is interesting. When I was using ILE, I didn't use service programs (which are basically just like Windows' DLLs), and I used CRTPGM's MODULE parameter to specify the, uh, modules.

If you are in the same place, then Service Programs with a Smile, Binder Source: The Little Language That Could and Customizing Your Development with Extensible RPG might be worth a read.
