1115: <file(module)> : '<symbol>'unresolved external 
------------------------------------------------------------------------------

  This message indicates that the '<symbol>', defined as external in
  module (module) of file <file>, cannot be found in any of the other .OBJ
  files or libraries in the script file. The usual cause of this problem
  is that an object or library file required by the program has been
  omitted from the script file. If not, this can usually be resolved by
  checking the order of the libraries to ensure that the library
  containing the missing external '<symbol>' comes after the module
  <file(module)> which is calling it.

  Another possible cause of this message is that some libraries require
  the use of the SEARCH command, as their library cross reference records
  are not complete.  Try a SEARCH on the library you suspect contains the
  missing '<symbol>'.  For a full description of the SEARCH command see
  Chapter 6.

  If you are aware of the cause for this message and want to continue
  linking to create an executable file, use the command BLINKER EXECUTABLE
  NODELETE.

  Clipper Summer '87

  If you get '__dos_hold' as an unresolved external then please check
  that you have the updated version of CLIPPER.EXE, CLIPPER.LIB and
  EXTEND.LIB from Nantucket (Summer '87).  The original versions all
  have a date of 12-21-87 and a time of 12:00 am (which may not be
  displayed), while the updated versions have the same date, but a time
  of 2:00am.  Blinker will work correctly only with the updated version,
  as there were a number of problems fixed in it.
