Ugh. I use functions when I can, but I could be using them a lot more. I would save a lot of code if I could use them like this without having to make them global:Local x:Int=10 ChangeX(x) Print x Function ChangeX(x:int) x=5 End Function Is there a way that I can use functions like this without making any Global variables? |

Yes.Local x:Int=10 ChangeX(x) Print x Function ChangeX(x:int var) x=5 End Function Adding var to the variable type in the function prototype ( as I've done in the code above ) passes it by reference instead of by value. |

Why did I not know of this?? Thanks! |

Because you didn't read the help files on the language carefully enough :) |

Yes, that would've helped me sooo much :) |
