Description:: Returns true only if one or both conditions are true. In case of the alternative syntax, lazy evaluation is used (if left operand is true, evaluation of the right side is skipped completely). Identical to: a || b
Multiplayer:: no special considerations
Groups:: Uncategorised

Syntax:: Boolean = a or 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 ((OBJ1) or (_enemycount == 0)) then {hint "you win !"}
Example 2:: if ((count _array == 0) or {(_array select 0) != player}) then {hint "It works! Without lazy evaluation it would throw an error if array was empty."}

IT07: The examples suggest that you can only use two conditions with or. You can use more if you want. It is not recommended to use a lot of conditions because the check will take longer to complete.
