# Preferences - System Variables

This preference panel allows you to view and modify ten system variables. These variables are accessible within actions and are retained when Yate terminates.

The panel displays single line representations of the system variables. However, it is possible that a system variable contains multiple lines of text. If a system variable contains a newline character, it will be displayed in blue. The Multi Line Editor will allow you to view and edit system variables in a larger multi line text field.
