## Example:

    Sub ExampleExit
    Dim sReturn As String
    Dim sListArray(10) As String
    Dim siStep As Single
        For siStep = 0 To 10 ' Fill array with test data
            sListArray(siStep) = chr$(siStep + 65)
            MsgBox sListArray(siStep)
        Next siStep
        sReturn = LinSearch(sListArray(), "B")
        Print sReturn
    End Sub

    Function LinSearch( sList(), sItem As String ) As Integer
    Dim iCount As Integer
    ' Linsearch searches a TextArray:sList() for a TextEntry:
    ' Return value Is the index of the entry Or 0 (Null)
        For iCount=1 To Ubound( sList() )
            If sList( iCount ) = sItem Then
                Exit For ' sItem found
            End If
        Next iCount
        If iCount = Ubound( sList() ) Then iCount = 0
        LinSearch = iCount
    End Function
