on how to move these VBA functions into VBA5:

Function Description
-------- -----------
Join Used to join arrays elements.

Split Split a string into a variant array.

InStrRev Similar to InStr but searches from end of string.

Replace To find a particular string and replace it.

Reverse To reverse a string.

The Split Function, quoted below gives a

Compile error: Automaton type not supported in Visual Basic

Public Function Split(ByVal sIn As String, Optional sDelim As _
String, Optional nLimit As Long = -1, Optional bCompare As _
VbCompareMethod = vbBinaryCompare) As Variant
Dim sRead As String, sOut() As String, nC As Integer
If sDelim = "" Then
Split = sIn
End If
sRead = ReadUntil(sIn, sDelim, bCompare)
Do
ReDim Preserve sOut(nC)
sOut(nC) = sRead
nC = nC + 1
If nLimit <> -1 And nC >= nLimit Then Exit Do
sRead = ReadUntil(sIn, sDelim)
Loop While sRead <> ""
ReDim Preserve sOut(nC)
sOut(nC) = sIn
Split = sOut
End Function

What's up with the error, and what can I do?
