extended legal file name characters |
The ODS-5 volume structure provides enhanced support for mixed UNIX and OpenVMS style file names. It supports long file names,
allows the use of a wider range of characters within file names, and preserves case within file names. With OpenVMS Alpha Version
7.3-1, the C RTL has greatly improved support of ODS-5 characters, with 250 of the 256 characters supported, as opposed to only 214
supported previously. Also, file names without file types can now be accessed.
To enable the new support, you must define one or more C RTL feature logical names. These names include the following:
DECC$EFS_CHARSET
DECC$DISABLE_TO_VMS_LOGNAME_TRANSLATION
DECC$FILENAME_UNIX_NO_VERSION
DECC$FILENAME_UNIX_REPORT
DECC$READDIR_DROPDOTNOTYPE
DECC$RENAME_NO_INHERIT
