Local File Names
The syntax of a local file name follows.
volume-name
is preceded by a dollar sign ($) and consists of 1 to 7 alphabetic or numeric ASCII
characters; the first character must be alphabetic; if volume-name is omitted, the
current default volume is used.
subvolume-name
consists of 1 to 8 alphabetic or numeric ASCII characters; the first character must
be alphabetic; if subvolume-name is omitted, the current default subvolume is
used.
file-name
consists of 1 to 8 alphabetic or numeric ASCII characters; the first character must
be alphabetic.
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 on which the file resides.
The syntax of a network file name follows.
system-name
is preceded by a backslash (\) and consists of 1 to 7 alphabetic or numeric ASCII
characters; the first character must be alphabetic.
volume-name
is preceded by a dollar sign ($) and consists of 1 to 6 alphabetic or numeric ASCII
characters; the first character must be alphabetic.
Notice that 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.
subvolume-name
consists of 1 to 8 alphabetic or numeric ASCII characters; the first character must
be alphabetic.
