Usage Notes
If you specify PATH=NO, you should also specify the NORMAL= parameter because if you are not looking for the path, you are not really interested in the connection. Basically, you're mainly interested in determining if the node is defined.
Conversely, if you specify PATH=YES to determine the type of connection to the next node, you must also specify all of the TYPEBSC=, TYPESNA= , and TYPETCP= parameters.
Do not use PATH=NO along with TYPEBSC=, TYPESNA=, and TYPETCP=, because unpredictable results will occur.
