Search for message file

The system searches for the message file from which the message description is retrieved.

The system uses the following two steps when searches are performed to retrieve a message from a message file:

1. The system processes any overrides that are in effect for the message file name.
2. If the message file name has not been overridden, the system searches for the message file based on the message file name and library specified when the message was used.

• System message file searches
  The message file name and library specified at the time the message file was sent are used to search for the message file from which the message description is retrieved.
• Override message files
  You can override message files used in a procedure or program.
