The NFS to OpenVMS file name translation rules in Table D-1 are based on the character mapping scheme in Table D-2. The OpenVMS to NFS mapping rules are the converse of these rules.

Table D-1 NFS Server to OpenVMS Client File Name Conversion Rules

Rule	What Happens to File Names from NFS to OpenVMS
1	Lowercase characters become uppercase (unless Rule 2 applies): file becomes FILE.;1
2	Initial uppercase characters or a sequence of case-shifted characters are prefixed with the "$" escape character: CaseShiftedFile becomes $C$ASE$S$HIFTED$F$ILE.;1
3	A file without a version gets a version number preceded by a semicolon: file becomes FILE.;1
4	If a file name does not include a dot (.), a dot is added before the version number semicolon: file becomes FILE.;1
5	After its name is converted, a file will not appear in an OpenVMS directory listing if any one of the following criteria are met: The file name is more than 39 characters long. The file extension is more than 39 characters long. The version number is greater than 32767.
6	If the file name has a dot, the dot is preserved unless the resulting file name fails one of the tests in Rule 5; if so, the dot becomes "$5N" and the same rule applies to each subsequent dot found: more.file.text becomes MORE.FILE$5NTEXT;1
7	If the file name is a directory, each dot becomes "$5N" and the file name gets the ".DIR" extension: dot.directory.list becomes DOT$5NDIRECTORY$5NLIST.DIR;1
8	Invalid OpenVMS characters become the escape character sequences in the second column of Table D-2 ("$" followed by a digit and a letter): special#character&file becomes SPECIAL$5CCHARACTER$5FFILE.;1 ("#" becomes "$5C" and "&" becomes "$5F")
9	Any existing "$" becomes "$$" (plus any "$" added due to Rule 2 or 8 above): dollar$Sign$5cfile becomes DOLLAR$$$S$IGN$$5CFILE.;1

Table D-2 provides a complete list of OpenVMS character sequences, corresponding server characters, and octal values used for NFS name conversion.
