Since I claimed to know a solution for a “specific dimensionality” in my question, I should prove this. See code below!

I would be happy to get your comments and criticisms on it. In specific I am interested in your experiences if you observe malfunctions. You may first run the test() Sub below and watch the variables in the BASIC IDE to check for my claims.

The now presented solution includes a short test. When I asked my question I had not yet had the idea with the ‘Redim-trick’. Originally there were nested For-loops with elementwise assignments. Now the code:

```
Function createArrayCopy2D(p2D)
If NOT IsArray(p2D) Then Exit Function
If NOT (dimensionality(p2D)=2) Then Exit Function
dummy = p2D
l = Array(Lbound(dummy,1), Lbound(dummy,2)
u = Array(Ubound(dummy,1), Ubound(dummy,2)
Redim Preserve dummy(l(0) To u(0), l(1) To u(1))
createArrayCopy2D = dummy
End Function
Function dimensionality(pArray)
dim d As Long ' The code relies on the initialization with 0.
If NOT IsArray(pArray) Then Exit Function
On Local Error Goto doneExit
Do
d = Ubound(pArray, d+1)*0 + d + 1
Loop
doneExit:
dimensionality = d
End Function
```

The test actually showed for me consistency with the “theory” I presented in the comments.

Edit1:

I missed to emphasize that references to other arrays contained in elements of the processed variant array (if any) are **not** dereferenced.

Edit2:

The above provided code was proven to fail in a different test done by a contributor in a different forum.

I tryed to fix the problem. Please visit **the other thread** for details.

Edit3:

I replacd the long code containing many lines of remarks by a shortened and slightly reworked version. There also is an enhanced version now inserted below, capable of handlig arrays with up to 5 dimensions.

To find the remarks again and also adiscussion, please visit the above given link.

```
Function createArrayCopy(pA)
If NOT IsArray(pA) Then Exit Function
dummy = pA
h = ArrayDimensions(dummy)
n = Ubound(h)
Select Case n
Case > 5
createArrayCopy = "Only up to 5 dimensions allowed!"
Exit Function
Case 1
Redim Preserve dummy(h(1)(0) To h(1)(1))
Case 2
Redim Preserve dummy(h(1)(0) To h(1)(1), h(2)(0) To h(2)(1))
Case 3
Redim Preserve dummy(h(1)(0) To h(1)(1), h(2)(0) To h(2)(1), h(3)(0) To h(3)(1))
Case 4
Redim Preserve dummy(h(1)(0) To h(1)(1), h(2)(0) To h(2)(1), h(3)(0) To h(3)(1), h(4)(0) To h(4)(1))
Case 5
Redim Preserve dummy(h(1)(0) To h(1)(1), h(2)(0) To h(2)(1), h(3)(0) To h(3)(1), h(4)(0) To h(4)(1), h(4)(0) To h(4)(1))
Case Else
createArrayCopy = "Unknow error!"
Exit Function
End Select
createArrayCopy = dummy
End Function
Function arrayDimensions(pArray)
If NOT IsArray(pArray) Then Exit Function
n = dimensionality(pArray)
Dim r(1 To n)
For j = 1 To n
r(j) = Array(Lbound(pArray, j) , Ubound(pArray, j) )
Next j
arrayDimensions = r
End Function
```
