statements like Dim AppEnd As Integer will generate compiler errors because Append is a special symbol/keyword in libreoffice basic. This restriction though is too strict because 'Append' is only such a keyword when used within the 'Open' statement ( where it refers to one of the possible values for a paramater ).
