Am I correct in my assumption that I can only pass arrays in the form of
variants to a procedure as a parameter.

For example, the following function always works for arrays
Function DoNothing(ByRef ArrIn as variant)
DoNothing = arrIn
End Function

While the following function never seems to work for arrays even if they are
dimensioned as integer arrays.
Function DoNothing(ByRef ArrIn as integer)
DoNothing = arrIn
End Function

Wayne C.

Sub Main()
Dim arr() As Integer
Dim v As Variant
ReDim arr(1 To 3)
For i = 1 To 3
arr(i) = i
Next
v = DoNothing(arr)
For i = LBound(v) To UBound(v)
Debug.Print i, v(i)
Next
End Sub


Function DoNothing(ByRef ArrIn() As Integer)
DoNothing = ArrIn
End Function


works for me.

No. Perhaps you are thinking about the parameters of a ParamArray array.

Your code snippet works when the array is called within a Sub. I have seen
and tried code snippets from other posts using the same approach you
outlined,but have never been able to get it to work as a worksheet function
call. If the function is used in a cell on an Excel worksheet and the array
values are called from a range on a worksheet, the result is the #VALUE error
message

For example, the values 1,2,3 are in Rows C3:C5 and named ArrIn. When
=DoNothing(ArrIn) or DoNothing(ArrIn()) is entered in Cell D7 , the result is
always #VALUE! .

Am I missing something?

ArrIn isn't an array. It is a range.

In that situation you could do

Public Function Test(arr As Range) As Variant
Dim vArr as Variant
vArr = arr.Value
Test = vArr
End Function

Assuming you wanted to do something to the values of the cells in the range
before you passed back the answer.

The above is simply wrong. Perhaps there is something in your code for
DoNothing that causes it. With 1,2,3 in C3:C5, which is named "ArrIn", with
Function DoNothing(whatever) As Integer
DoNothing = Application.Sum(whatever)
End Function

then on the worksheet =DoNothing(ArrIn) returns 6
