Description : Vbscript function that sorts an one-dimensional array of number either ascending or descending. This function sorts using the well known double for..next principle. Script gives an overview of passing parameters and especially passing arrays of numbers to a function.

'--------Begin Function----
Function fnSort(aSort, intAsc)
Dim intTempStore
Dim i, j
For i = 0 To UBound(aSort) - 1
For j = i To UBound(aSort)
'Sort Ascending
If intAsc = 1 Then
If aSort(i) > aSort(j) Then
intTempStore = aSort(i)
aSort(i) = aSort(j)
aSort(j) = intTempStore
End If 'i > j
'Sort Descending
Else
If aSort(i) < aSort(j) Then
intTempStore = aSort(i)
aSort(i) = aSort(j)
aSort(j) = intTempStore
End If 'i < j
End If 'intAsc = 1
Next 'j
Next 'i
fnSort = aSort
End Function 'fnSort
