Code Returns
List of individual variables
API DeclarationsPublic Type TokenList
Tokens() As String

Dim iCount As Integer
Dim iStart As Integer
Dim iTokens As Integer
ReDim Tokenize.Tokens(0)
iTokens = 0

Do Until iCount = Len(strString)
If Mid$(strString, iCount, Len(strSeparator)) = strSeparator Then
ReDim Preserve Tokenize.Tokens(iTokens + 1)
