Why Can't My WebSphere Application Development Teams Get Along? They can, with Enterprise Application Management (EAM)!
With WebSphere application development products, synchronizing work across multiple enterprise platforms is difficult and time-consuming. Project teams must meet frequently to determine the readiness of independent components. Now, EAM can dramatically dramatically improve your WebSphere development teams' productivity by coordinating multi-tier application development across multiple teams.

The call of the prototype
[Search400.com]
by Paul Tuohy
A lot of RPG programmers are under the misconception that the CALLP operation means Call Procedure. That is because most of them come across it when they start using subprocedures. But CALLP means Call a Prototyped Procedure or Program, and it can be used in place of the CALL operation, as well as CALLB.
This week I want to discuss the benefits of prototyping dynamic calls.

Using CALLP with an existing program
[Search400.com]
"Okcpgmr" was trying to call an existing program from another using the CallP opcode, but he ran into problems. Thanks to the help from a couple other users, he figured out what was going on.
Send an e-mail to an admin when a job gets a status of *MSGW
[Search400.com]
See how this user incorporates CALLP in his program to help see if any iSeries jobs have a status of *MSGW. Then, when the job gets a status of *MSGW, the program sends an e-mail to an administrator.
Don't proliferate old, bad code
[Search400.com]
In an effort to hasten the completion of projects, most programmers "steal" code from other sources within their libraries. The problem is that many times, the code originated years ago and is cumbersome, lengthy and not easy to maintain. Even most ILE code resulted from old code that was passed through a conversion utility. Using the functionality of RPG IV's keywords and built-in functions usually can make the code much smaller
and manageable.
