STATEFULL calling of RPG programs is great!

I also need to call RPGLE service programs from EGL. I just completed the IBM EGL Distance Learning class last week. The course material (available http://www.jsayles.com/ibm/) covered RPG program calls but not service programs. I e-mailed Jon Sayles this morning with that question.

Heeee! You can thank me for that, Justin. Well, you can thank the EGL team and in particular a brilliant gentleman by the name of Joe Vincens who listened to me as I ranted on and on about the need for stateful connections <grin>. But once I made my point clear (about how a stateful connection allows me to keep cursors open and all that jazz on the server) he was absolutely on board and they made it happen.

With stateful calls, I can make hundreds of round trips between EGL and RPG in a second. It's really quite brilliant, and by far the fastest way to write and expose complex business logic. SQL is nice when you have to read a bunch of records, but as soon as you have to do complex logic, RPG is the way to go!
