Internal Error #415

  (#101160) Error opening dynamic file.  Occurs when you compile a file
  and link with first object module name longer than 8 characters.

  This is a problem with RTLINK.EXE, not with CLIPPER.EXE.  The problem
  involves specifying an object filename longer than 8 characters.  The
  extra characters are ignored during file access, so the link works, but
  the EXE has the extra characters in its reference to itself for VMM and
  dynamic code swapping.  When you run the application, and it attempts to
  load another part of itself, it can't because the internal file name is
  invalid.

  Solution: Don't use longer than 8 characters for filename.
