This happens because of the cascading nature of [https://en.wikipedia.org/wiki/Recursion_(computer_science) recursion], inner-level functions create variables of the same name, thus they are of the same name and a lower scope, therefore the engine treats them as though they are the same variable. [[params|Params]] gets around this, most likely, by creating a new, unique application-level variable under the hood, despite being of the same name.

If expectedDataTypes is excluded does the command use the default value as the expected data type? --SS (talk) 03:01, 17 July 2015 (CEST)

What? The command doesnt need to check data types if data type checking isnt used...Benargee (talk) 03:20, 17 July 2015 (CEST)
Thanks, that answers my question SS (talk) 13:34, 17 July 2015 (CEST)

Params really shines when used in recursive functions. _myTestVar = 0; systemChat str _myTestVar; _myTestVar call { _myTestVar = _this + 1; _myTestVar call { _myTestVar = _this + 1; } }; systemChat str _myTestVar; Outputs 0 2 0 params ["_myTestVar"]; systemChat str _myTestVar; _myTestVar call { (_this + 1) params ["_myTestVar"]; _myTestVar call { (_this + 1) params ["_myTestVar"]; } }; systemChat str _myTestVar; Outputs 0 0
