Is there an easy way to split an array into 2 smaller arrays.
For example:
FullArray(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15)
Split this array into 2 arrays with first array containing the first 10 items and the second array containing the remaining items.
SizePart1 = 10
SizePart2 = UBound(FullArray) - SizePart1

The 2 new arrays would be like this;
ArrayPart1(1,2,3,4,5,6,7,8,9,10)
ArrayPArt2(11,12,13,14,15)​
All arrays are one dimensional and contain only numbers. They are VBA arrays, not Excel columns.
 

Excel Facts

Why are there 1,048,576 rows in Excel?
The Excel team increased the size of the grid in 2007. There are 2^20 rows and 2^14 columns for a total of 17 billion cells.
Hi,

The obvious way is to create two arrays of the correct size then use a For/Next loop to populate them.

If you want to be more adventurous and if you are using Windows then you could try an ArrayList object. This does some things like a conventional array, it does not do some things that an array does and it does some things that an array can't do - sub-setting and sorting, for instance. Try this:
Code:
Sub GetRange()

    Dim myAL As Object
    Dim mySubAL As Object
    Set myAL = CreateObject("System.Collections.ArrayList")
    Set mySubAL = CreateObject("System.Collections.ArrayList")

    myAL.Add ("The")
    myAL.Add ("quick")
    myAL.Add ("brown")
    myAL.Add ("fox")
    myAL.Add ("jumped")
    myAL.Add ("over")
    myAL.Add ("the")
    myAL.Add ("lazy")
    myAL.Add ("dog")
    
    
    Set mySubAL = myAL.GetRange(2, 4)
    
    MsgBox Join(myAL.ToArray(), vbNewLine)
    MsgBox Join(mySubAL.ToArray(), vbNewLine)
        
End Sub
