Last time, I discussed and demonstrated some of the uses for which IBM i message descriptions provide a flexible and versatile foundation (“Copying System i Message Descriptions,” March 26, 2009, article ID 57897 at SystemiNetwork.com). Today, I continue the coverage of IBM i message descriptions and focus on some of the purposes the operating system and its components use message descriptions for.
As usual, I also provide a utility involving the use of one or more APIs related to the topic at hand. Because today’s article investigates IBM i’s employment of message descriptions, I’ve created a CL command that helps you find message descriptions based on generic message IDs as well as a text string in either the message description’s message text or second-level text. I’ve named the command Find Message Description (FNDMSGD).
