For an interactive or batch client, the WRITE-MESSAGE( ) method writes the log entries to the log file specified by the LOGFILE-NAME attribute or the Client Logging (-clientlog) startup parameter. For WebSpeed agents and AppServer servers, the WRITE-MESSAGE( ) method writes the log entries to the server log file. For DataServers, the WRITE-MESSAGE( ) method writes the log entries to the log file specified by the DataServer Logging (-dslog) startup parameter.
A character expression or variable representing the message to write to the log file.
subsys-expr
A character expression representing the subsystem identifier to write to the log file. The default is "APPL". You can provide your own subsystem identifier. The subsystem identifier has a character limit 10 characters, and is padded to 10 characters. If you provide a subsystem identifier longer than 10 characters, WRITE-MESSAGE( ) writes only the first 10 characters.
If the WRITE-MESSAGE( ) method succeeds, it returns TRUE. If it fails, it returns FALSE.
If there is no client log file, the WRITE-MESSAGE( ) method returns FALSE and displays a warning message indicating this operation is not valid when there is no log file. For an interactive or batch client, the WRITE-MESSAGE( ) method writes the warning message to the current output device.
When the client writes messages using the WRITE-MESSAGE( ) method, the component identifier in the message header is the default component identifier for the client executable writing to the log. For example, the component identifier for a GUI or character client is "4GL", for WebSpeed is "WS", and for AppServer is "AS". You can provide your own subsystem identifier. The default is "APPL". The subsystem identifier has a character limit of 10 characters, and is padded to 10 characters.
