    Info: This call is identical to DOS Fn 3cH (create file), except that
          it will fail if the file already exits on the named drive and
          directory.

          DS:DX points to an ASCIIZ string in the form...
             d:\path\filename.ext0
          If the drive or path is omitted, defaults are assumed.

          The file is opened for read/write in compatibility Access Mode.

          Fn 6cH has a options which include this capability.
