  Association tables provide a way of storing data locally and accessing by ID.  XLookUpAssoc() retrieves the data stored in  an  XAssocTable
  by  its  XID.  If the matching XID can be found in the table, the routine returns the data associated with it.  If the x_id cannot be found
  in the table the routine returns NULL.

  For more information on association tables, see Volume One, Appendix B, X10 Compatibility.
