Array variable setup

I want to create a multi dimential dynamic array variable called Status() as shown below.  

Status(Row, MorN, NoOrState, DateModYN)

Sub Test1() works okay. But Test2() errors at:  ReDim Preserve Status1(2, 2, 2, 2) '*********

How can I correct this?

Thank you.


Sub test1()
 
    Dim Status1() As String
    ReDim Preserve Status1(1, 2, 2, 2)
 
    Status1(1, 1, 1, 1) = "101"
    Status1(1, 2, 1, 1) = "N"
    Status1(1, 1, 2, 1) = "No"
    Status1(1, 1, 1, 2) = "ModY"
 
    MsgBox Status1(1, 1, 1, 1)
    MsgBox Status1(1, 2, 1, 1)
    MsgBox Status1(1, 1, 2, 1)
    MsgBox Status1(1, 1, 1, 2)
 
End Sub
 
Sub test2()
 
    Dim Status1() As String
    ReDim Preserve Status1(1, 2, 2, 2)
 
    Status1(1, 1, 1, 1) = "101"
    Status1(1, 2, 1, 1) = "N"
    Status1(1, 1, 2, 1) = "No"
    Status1(1, 1, 1, 2) = "ModY"
 
    MsgBox Status1(1, 1, 1, 1)
    MsgBox Status1(1, 2, 1, 1)
    MsgBox Status1(1, 1, 2, 1)
    MsgBox Status1(1, 1, 1, 2)
 
    ReDim Preserve Status1(2, 2, 2, 2) '*********
 
    Status1(2, 1, 1, 1) = "102"
    Status1(2, 2, 1, 1) = "N1"
    Status1(2, 1, 2, 1) = "No1"
    Status1(2, 1, 1, 2) = "ModY1"
 
    MsgBox Status1(2, 1, 1, 1)
    MsgBox Status1(2, 2, 1, 1)
    MsgBox Status1(2, 1, 2, 1)
    MsgBox Status1(2, 1, 1, 2)
 
End Sub

I want to increment ---v
                      Status(Row, MorN, NoOrState, DateModYN)

The others (MorN, NoOrState, DateModYN) will remain 2 always.

This might be it - from the Help File **** --- ****:

"If you use the Preserve keyword, you can resize only the **** last array dimension *** and you can't change the number of dimensions at all. For example, if your array has only one dimension, you can resize that dimension because it is the last and only dimension. However, if your array has two or more dimensions, you can change the size of only the last dimension and still preserve the contents of the array. The following example shows how you can increase the size of the last dimension of a dynamic array without erasing any existing data contained in the array.

ReDim X(10, 10, 10)
. . .
ReDim Preserve X(10, 10, 15)

Similarly, when you use Preserve, you can change the size of the array only by changing the upper bound; changing the lower bound causes an error."

So, instead of Status(Row, MorN, NoOrState, DateModYN) I can have:

Status(MorN, NoOrState, DateModYN, Row)

Because I will need to resize only Row. I will try it on Monday.

Thanks,

Mike
