  In the current issue of ACM SIGAda Ada Letters, there is an article by
  Y.E. Gail Wang (pages 111-117) which reports on a set of Ada components
  designed to provide filename portability between MS-DOS, Unix, and VMS.  

  UNIVERSAL_FILE_NAMES was developed under a STARS contract, and provides
  Ada filename portability such that it is unnecessary to change filenames
  or filename paths when porting software among the above-listed operating
  systems.  The UFN system, 1100 lines of Ada code, is itself directly
  portable among all of these operating systems -- it does not require 
  the support of any sort of non-portable operating system interface. 

  The universal file/path naming allows programmers to use up to 79
  characters in each file or directory name, regardless of the number
  of filename characters actually supported by the underlying file system.
