Network File Names
Network File Names
Network file names identify files that are accessed across a network of HP NonStop
systems. Always identify a network file by a fully qualified file name that includes the
system, volume, and subvolume.
system-name
is one alphabetic character followed by up to 6 alphanumeric ASCII characters.
volume-name
is one alphabetic character followed by up to 6 alphanumeric ASCII characters.
subvolume-name
is one alphabetic character followed by up to 7 alphanumeric ASCII characters.
file-identifier
is one alphabetic character followed by up to 7 alphanumeric ASCII characters.
Locale Names
The DDL compiler recognizes locale names for internationalization support. Using the
clause LN
on page 6-13, you can specify the language, territory, and character set for
a text item. See Table 6-3, Supported Locale Names,
on page 6-14.
\system-name.$volume-name.subvolume-name.file-identifier
Note. The maximum number of characters in the volume name of a network file is less
than the maximum for the volume name of a local file: only 6 characters plus the dollar
sign rather than 7 characters plus the dollar sign for a local volume.
