Define messages and message help

You can define two levels of messages on the Add Message Description (ADDMSGD) command. The text of the message is required and should identify the condition that caused the message to be issued. Message help is optional and should explain the condition further or explain the corrective action to be taken.

To get message help, the display station user must move the cursor to the message line and press the Help key when the message is displayed. Message help can be formatted for the display station using three format control characters. These characters may be used to make the message help (usually online help information) more readable for the user.

Each of the three format control characters must be followed by a blank to separate them from the message text.

&Nb (where b is a blank): Forces the text to a new line (column 2). If the text is longer than one line, the next lines are indented to column 4 until the end of the text or until another format control character is found.
&Pb (where b is a blank): Forces the text to a new line, indented to column 6. If the text is longer than one line, the next lines start in column 4 until the end of the text or until another format control character is found.
&Bb (where b is a blank): Forces the text to a new line, starting in column 4. If the text is longer than one line, the next lines are indented to column 6 until the end of the text or until another format control character is found.
