February 2001 Monthly Meeting

Greg Veal Puts the "Popcorn"

in Message Handling

If you’re interested in learning about AS/400 message handling in an entertaining format, don’t miss our special “double feature” presentation at the February 20th meeting.  OK, so they’re not really movies! But, CL expert and author, Greg Veal, uses graphical techniques to help you understand how AS/400 message handling really works.

The first “flick”, “AS/400 Message Handling – the Movie”, covers important message handling basics including: the Job Message Queue, Sending and Receiving Messages, Basic Error Handling, Interpreting MSGDTA and SENDER data, and Break-Handling Programs.

After intermission, we’ll enjoy a showing of Greg’s medal-winning COMMON presentation, “AS/400 Message Handling – the Sequel”.  In this advanced, silver screen attraction, Greg uses more graphical techniques and lots of CL & DDS code examples to give you insight into how message handling makes the AS/400 tick. Among other fascinating techniques, you’ll learn about the “Miracle” of Request Processing, how to write a standardized Error Handling Program that always works, and how to run impromptu commands in batch (or in any other) jobs. (It’s all done with Mirrors Messages!)

So, get yourself some Jujubes and popcorn and join the fun!
