Example of Retrieving Event
Messages
This appendix presents a complete working example of a management application in
four versions: a TAL version, a TACL version, a COBOL version, and a C version. The
example includes a filter specification and a DDL file.
The four versions of the example have DDL and filter source files in common but
require distinct main source code files.
When you run this application at your terminal, it displays the event messages that
originated in a particular CPU of your system. The application prompts you for the CPU
number and reads and displays event messages as they are logged by the collector.
Execution of the application continues until you press the BREAK key at the terminal
and stop the application with a STOP command.
