Optional. If you do not wish to use an error message file (refer to Error Message Number, File and Library) to store the message text, then you may enter the text of the error message to be displayed directly. If this facility is used then the message will have no second level text associated with it. Refer to Messages and the Help Key.
If neither an error message number, file and library nor error message text is specified LANSA will insert a default error message number, file and library as the error message. These default messages are "general purpose" and do not provide much detail about the specific cause of the error.
