+Assigning variables
+--------- ---------
+
+As of rAthena revision 15982, variables can be accessed and assigned values directly
+without the use of the built-in 'set' function. This means that variables can be
+accessed and modified much like other programming languages.
+
+    @x = 100;
+    @x = @y = 100;
+
+Support for modifying variable values using 'set' is still supported (and required
+to exist for this new method to work) so previous scripts will continue to work.
+
+When assigning values, all operator methods are supported which exist in the below
+'Operators' section. For instance:
+
+    @x += 100;
+    @x -= 100;
+    @x *= 2;
+    @x /= 2;
+    @x %= 5;
+    @x >>= 2;
+    @x <<= 2;
+
+Will all work. For more information on available operators, see the Operators section
+described below. All operators listed there may be placed in-front of the '=' sign
+when modifying variables to perform the action as required.
+
+Note:
+
+ !! Currently the scripting engine does not support directly copying array variables.
+ !! In order to copy arrays between variables the use of 'copyarray' function is still
+ !! required.
