Description:: Returns "true" only if both conditions are true. In case of the alternative syntax, lazy evaluation is used (if left operand is false, evaluation of the right side is skipped completely).
Multiplayer:: no special considerations
Groups:: Uncategorised

Syntax:: Boolean = a and b (Only available since ArmA 2:OA v1.62.)
Parameters:: a: Boolean - Test condition or variable that returns Boolean.
: b: Code - Code that returns Boolean. It is not evaluated if a returns as true.
Return Value:: Boolean

Example 1:: if ((alive player) and (_enemycount == 0)) then {hint "you win !"}
Example 2:: if ((count _array > 0) and {(_array select 0) == player}) then {hint "It works! Without lazy evaluation it would throw an error if array was empty."}
