DECC$EFS_CASE_SPECIAL

   With DECC$EFS_CASE_SPECIAL enabled, case is preserved only for
   filenames containing lowercase. If an element of a filename
   contains all uppercase letters, it is reported in all lowercase
   in UNIX style.

   When enabled, DECC$EFS_CASE_SPECIAL overrides the value of
   DECC$EFS_CASE_PRESERVE.
