'System Values' are special read-only, global variables that provide information about the state of the current player and the world. e.g. $gPlayerAge tells you the age of the current player. Here's a quick example of how you might use that

<codedoc>

$myvar = $gPlayerAge + 1
*say Next birthday, %PLAYER% will be $myvar years old

</codedoc>

Here is the full current list of System Values:

These values give details about the player the current event is executing for.
For further details on each value, see the Player Stats Reference
