Several state variables are used. The primary state variable, unimaginatively called State, indicates the type of information displayed on the LCD: status, log, or menu. There are also states for the brief Command Sent message and for an indication that the program could not open an SQL connection to the ladd daemon. Another state variable, Curcmd, contains an integer that indicates which command to show when the user is in the menu. The Command button cycles Curcmd through the five possible front panel commands. The Zone state variable holds the zone number to use for the current command. The Zone button cycles Zone through the five possible zone numbers.
