Sorting Arrays Ascending or Descending
This is a sub-routine that can sort an array in ascending or descending order. It works by running the array, then as a temporary variable is holding the value of that item, it loops through the array again an compares the temporary value to all the other values in the array and reassigns the temporary value to the current array number depending on of you are sorting it ascending or descending. You could compare it to a ladder. The sub-routine will move the temporary value up or down the ladder accordingly and shift the other values in the array to make room for it.
In the example below, I have two methods of declaring arrays and how to use them with this sub-routine.

Here is the ASP code for this script:
```

<%

Sub SortArray(TheArr,AscDesc)

TempVal = ""

For x = 0 to UBound(TheArr)

For y = x+1 to UBound(TheArr)

If AscDesc = "Desc" Then

If TheArr(x) < TheArr(y) then

TempVal = TheArr(y)

TheArr(y) = TheArr(x)

TheArr(x) = TempVal

End If

Else

If TheArr(x) > TheArr(y) then

TempVal = TheArr(x)

TheArr(x) = TheArr(y)

TheArr(y) = TempVal

End If

End If

Next

Next

End Sub
