Function NWcreateTAB(filename: string; nodelayer: boolean): integer;
The topological network is created from a MapInfo TAB file (tab).
See NWcreate for details.
Input: Filename should be without extension and the location of the file is determined by property Directory.
If nodelayer=true then function NodeCreate is called at the same time.
If you are using an affine coordinate system, it will not be detected and the coordinate clause will be wrong. Due to the status of the TAB-format (no official description), the network created may be faulty. If you encounter any problems, please report to RouteWare.
