  -_*Constructing a Message Format*_
  +*Constructing a Message Format*
   
   In a Message Format, any word surrounded by $-signs represents a variable, the value of which will be determined when the message is generated during play. When constructing a Message Format for a component, click the *Insert* drop-down menu for a list of available variables for the Message Format. Selecting one of the variables from the menu will insert it at the current cursor position.
   
  
positive.code: 
  Property names are case-sensitive. For example, PowerLevel is not the same Property as powerLevel.
  
  _*Property Values*_
  
  *System Property Values:* System Properties automatically take their values from the game state. You wonʼ t need to assign values to System Properties manually (in fact, you cannot do so). Their values will depend on the condition they describe. For example, the value of the CurrentBoard Property for a Game Piece is the name of the current Board where the piece is located. If you moved the piece to a new Board, the value of CurrentBoard for that piece would change automatically to the name of the new Board.
  
  
negative.code: 
  A Game Piece cannot directly access:
  
  * Properties on another Game Piece.
  * Zone Global Properties on a Zone that the Game Piece is not currently located in.
  * Map Global Properties on a map that the Game Piece is not currently located in.
  
  For most components, system Properties are hardcoded as part of the VASSAL engine. However, for Game Pieces, you can create entirely new Properties using the Dynamic Property, Marker, and Property Sheet Traits. See _Game Piece Traits_ on page 42 for more information.
  
  === Message Formats
  
  Many Traits and module components enable you to customize the message that is displayed to users in the Chat Window when game events take place. A _Message Format_ is a formula for creating such a message to players. Message formats are highly customizable and usually include Properties as variables.
