Description:
A Boolean can either be true or false. Note that Booleans are real types in the scripting language.

In config.cpp (addons), a boolean is simply a poetic licence, a convenience, for a zero/non zero integer.

-Boolean ([[true]] or [[false]]).
+A [[Boolean]] can either be [[true]] or [[false]].
+Note that Booleans are '''real''' types in the scripting language.
-Boolean values in OFP are ''identical'' to [[Number|numbers]] except, by convention, the values are 0,  or 1. In fact, the engine when dealing with boolean variables (token-names) is happy with 0, and any other value.
+In config.cpp (addons), a boolean is simply a poetic licence, a convenience, for a zero/non zero integer.

- StartEngine = 0; // would be interpred as off
- IsNightTime = 1; // is not daytime !!!
-as a covenience. well written mission.sqm's and well written config.cpp's (addons) have the following defines at top of file
- #define true 1
- #define false 0  // note the lack of a semicolon
-Thus the script fragment
- IsNightTime=true;
-is exceedingly more readable, with the added bonus that not all token-names (IsNightTime) 'look' like boolean names. They could, appear to be, to the human reader, an integer that can take any value.
