Another way would be to add a command "ByRef", At the stage you call ByRef input , "input" doesn't contain a reference to the caller's variable, so what would you expect it to do? I would expect it to add such a reference, but I personally prefer the 1st suggested variant: adding ByRef to the argum...

Well you could do it the other way around, however you would have to rewrite the function and have it accept ByRef parameter(s). If you need to pass a variable not ByRef then you just have to pass an expression: v := "Hello World" f(v) f([v][1]) f(ByRef arg) { MsgBox % "arg is " . (IsByRef(arg) ? "...

I will, as soon as all commands that get some data and store it into a var will store the data into an object.
Why are you so against the proposed change?
How often do you make functions calls like func(byref var) so that the proposed change would break something for you?

The only difference with the current Sort command is that Dx param will be useless/unusable.

Now, that second one is something you can already do with language constructs. nullify(ByRef input, ByRefyInput) { tmp := input tmp := 0 if ByRefyInput input := tmp } Yes, but that's an unwanted complication. I could as well duplicate the function: nullify(a, b){ a := b := 0 } nullifybyrefa(ByRef a...

Could you provide a context in which this would be useful? This lets to create way more universal functions and use less variables (and thus less memory and less manual garbage collections). result := multiply(multiplicator1, multiplicator2) multiply(ByRef result, multiplicator2) multiply(a, b){ a ...

Another way would be to add a command "ByRef", that would quite act like "Global" or "Static" commands, buw would be usable only inside of a function: foo := 1 nullify(foo) MsgBox, %foo% ; 1 nullify(foo, 1) MsgBox, %foo% ; 0 nullify(input, ByRefyInput = 0) { If ByRefyInput ByRef input input := 0 }

Provide a way to forcefully make an attribute a 'ByRef' from a call to a function with non-ByRef attribute: The above script should yield 0, not 1.

You are right, kon. Shame on me.

Drag'n'drop n (where n > 1) files onto a script with such a code: MsgBox should show n, but instead it shows the path to the 1 of the dropped files.
Bug happens to me on latest release version.
