Controlling System Messages
You can prevent system messages from being issued, based on their severity level. FormsBuilder classifies every message with a severity level that indicates how critical or trivial the information is; the higher the numbers, the more critical the message. There are six levels that you can affect.

Note: Suppressing Messages According to Their Severity
In a trigger, you can specify that only messages above a specified severity level are to be issued by the form. You do this by assigning a value to the
MESSAGE_LEVEL
system variable. Forms then issues only those messages that are above the severity level defined in this variable. The default value for
MESSAGE_LEVEL
(at form startup) is 0. This means that messages of all severities are displayed.
