Full_Support

   OpenVMS utilities and commands that offer full support for ODS-5
   have been specifically modified to take advantage of all the
   features of extended file naming. These utilities and commands
   should accept and handle extended file specifications without
   error and without modifying their expected case.

   In addition, OpenVMS commands and utilities that fully support
   Extended File Specifications can accept and produce long file
   specifications that exceed the traditional 255-byte limit in
   their original form-without requiring them to be abbreviated in
   Directory ID (DID) or File ID (FID) format.
