Message code

The message code consists of seven characters. The first three letters are the message class and the final four characters are the message number.
The message class designates, for example, a BS2000 component, a subsystem or a module; the message number is used to number messages consecutively within a message class.
The message number usually consists of four numeric characters. Messages whose message number also contains letters are placed in the message file in front of messages whose message number contains only numeric characters.

Example

The message codes ABC123A through ABC123Z appear before the message codes ABC1230 through ABC1239 in the message file.
