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 ignored.
Alias:: a && b
Groups:: Variables Math

Syntax:: a and b
Parameters:: a: Boolean - Test condition or variable
: b: Code - Code that returns Boolean. It is not evaluated if a is false
Return Value:: Boolean

Example 1:: if ((not isNull player) and (alive player) and (_enemycount == 0)) then { hint "you win !"; };
Example 2:: if ((count _array > 0) and { (_array select 0) == player }) then // works as expected { hint "It works!"; }; if ((count _array > 0) and (_array select 0) == player) then // Error: _array select 0 is evaluated { hint "It... works?"; };
