Passing array to function

Blitz3D Forums/Blitz3D Beginners Area/Passing array to function

Hi, I try to call a function like this:

displayArray(map,4,4)

But it is not allowed.
This is the function:

Function displayArray(whichArray,amountX,amountY)
For y = 0 To amountY
For x = 0 To amountX
Text x*20,y*20,whichArray(x,y)
Next
Next
End Function

How should I call the function and/or type the head of the function?

Thank you.

An array cannot be a function parameter. (The exception is a "BlitzArray", using [] -- search the forums for it.)

Since arrays are global, you can use it in the function, but you can't pass it in as an argument.

I'd also point out that each type effectively comes with a dynamic array and that this tends to obviate the need to pass arrays around (or use arrays much).

...each type [of array] effectively comes with a dynamic array...

What does this mean? I don't understand.
