Proper format for dimensioned variable?

Recommended Posts

qwert

I'm using a call that returns an array -- WinGetPos -- for the very first time.

The documentation describes the call this way:

$size = WinGetPos("")

MsgBox(0, "Active window stats (x,y,width,height):", $size[0] & " " & $size[1] & " " & $size[2] & " " & $size[3])

What is the proper way to declare the $size variable?

Dim $size [0] [1] [2] [3] doesn't work and the "Dim" documentation doesn't show a clear case.

Thanks in advance.

If you want to declare a one-dimensional array as in the example, you'd declare each value as such:

Dim $size[0] = 10
Dim $size[1] = 10
Dim $size[2] = 10
Dim $size[3] = 10

The number in [] brackets is the position of the value in the array.

Thanks.

So there's no single-line statement to declare a small array if no initial values are needed?

If no values are needed, you can define an array based on how many values it will have within it. For example:

Global $size[3]

Would allow you to assign values to $size[0], $size[1], $size[2], and $size[3]. Something like $size[2000], for instance, would allow you to populate up to 2001 values into the array.

When you use a function, such as WinGetPos(), the array will usually define itself, without the need of a Dim statement.

However, is cases in which the array is not defined, Dim can be used like this:

Dim $array[4]

This will create a 1-Dimensional array with the following definable values.

$array[0]

$array[1]

$array[2]

$array[3]

Note, there are 4 total elements in the array, however because it is zero-based the last element in the array is referenced by the number 3, despite it being the fourth element.

Hope this helps

Yes, that's the full explanation I was hoping for.

Thanks very much.
