Example 6:

Get current value of a variable and if it is undefined, define it and get the defined value:private _var = missionNamespace getVariable "varName"; if (isNil "_var") then { missionNamespace setVariable ["varName", 123]; _var = 123; }; // _var here will contain current value of the variable varName

NOTE: Arma 2 ONLY! In Arma 3 this will return default value: Warning: the alternative syntax returns undefined when the varspace is an object and that object is null. Example:
_test = objNull getVariable ["test", "0"]; systemChat _test; Errors because _test is undefined. Tested in A2OA 1.63.131129

You can do typechecking using param: private _myVar = [player getVariable "myVar"] param [0, "", [""]]; and params: [player getVariable "myVar"] params [["_myVar", "", [""]]];
