1109:  unable to open file <filename> 
------------------------------------------------------------------------------

  This message indicates that Blinker was unable to find the specified
  file in the current directory where it was expected to be, so the full
  directory path for the file should be specified.  If no file extension
  is specified for script files, Blinker assumes an extension of .LNK.

  If the file is an .OBJ file then check the OBJ environment variable, or
  if it is a .LIB file, check the LIB environment variable. For more
  details on all the files used by Blinker check the Input/Output section
  in Chapter 3.

  This error can also occur when Blinker is attempting to create a swap
  file and the TEMP environment variable points to an invalid directory.
  When running on a network, it is also possible that another user deleted
  the file or that you do not have network access rights to the file.
