How to replace Arrayname in function?

[Cainnech]

Hey guys,

I've got a question about arrays and I think it's related to the data types.

I want to construct a generic function that I can use on multiple arrays.
Basically I've got a number of arrays which I need to fill. To do that I created a generic function that adds a value to an array.

Now I'm trying to put the Arrayname also in that function so that I only have to call the function with the name of the array and the value and the value is inserted in the array.

I'll give you the code to make myself clear:

function AddToArray(arr, value)

    if ubound(arr) = -1 then

      ReDim arr(0)
      arr(0) = value

    else

      ReDim Preserve arr(ubound(arr) + 1)
      arr(ubound(arr)) = value

    end if


end function

Dim output 
output = Array()

AddToArray("output", "AnyGivenValue")

The problem probably lies in the name of the array that I'm sending to the function. Here I put it in brackets like it is a string, but I know it's not. It's an array.

Anybody have any ideas on how to solve this?

Thanks.

Ah, found it after much looking around.

AddToArray(output, "AnyGivenValue")

Should have been:

AddToArray output, "AnyGivenValue"

The brackets were not neccessary.

Mmm. Function calls should have their argument in brackets, but as you are not assigning the value of the function to a variable you should be using

Call AddToArray(output, "AnyGivenValue")

However, it's not the brackets that made the real difference - you didn't mention that you've removed the double-quote marks from the array name too, as indeed was essential. You are then passing the array itself by reference to the sub as a dynamic array argument, instead of the name of the array.

Trying to pass the name of the array was a blind alley for you, as you can't recover the array itself from its name; you did indeed need to pass the array by reference instead.

When you wish to pass arrays of differing dimensions you must use a dynamic array argument, as you are doing in line 19 of post 1.
