constant array
 

Is there a way to defind an array of constants in VBA? I
tried the following and it would not compile.

Const a(1) As Double = 1
Const a(2) As Double = 2

Thanks,
Sam

one way:

Sub LoadArray()
Dim aA(1 To 5) As Double
Dim i As Long
For i = 1 To UBound(aA)
aA(i) = i
Next 'i
'For i = 1 To UBound(aA)
' Debug.Print i & " " & aA(i)
'Next 'i
End Sub

As I recall, you can't use the Const Keyword with an array.

Trevor,
Thanks for the suggestion. I want to avoid a call to a
procedure to do this. My specific problem is this: in
calculating the positions of the planets, I have to
evaluate a series of terms in the form A*Cos(B+C*t), where
A, B, and C are constants. This does not look too bad to
code in-line. However, when I have to sum anywhere from 32
to 64 of these, I could save myself a lot of problems if
the constants are in a array. My goal is to load the
constants into the array at compile time and not at run time.

Regards,
Sam

The direct answer to your question is No.

You can do this, which is sort of close in a way, kind of but not really.

Sub Main()
Const s As String = "1,2,3,4,5"
Dim v As Variant, i As Integer
v = Split(s, ",")
For i = LBound(v) To UBound(v)
Debug.Print v(i)
Next i
End Sub
