Directory_Naming_Syntax

   When using Extended File Specifications, directory names conform
   to most of the same conventions as file names when using the
   ISO Latin-1 character set. Periods and special characters may
   be present in the directory name, but they must be preceded by a
   circumflex (^) in order to be recognized as literal characters,
   as shown in the following table:

   CREATE/DIRECTORY. . .       Result

   [Hi^&Bye]                   Hi^&Bye.DIR;1
   [Lots^.Of^.Periods^.In^.ThisLots^.Of^.Periods^.In^.This^
                               .Name.DIR;1
