Time Variable
Time Variable
The variable time is used for attributes that require a specified time interval. The
syntax of time is:
hours
specifies an integer, as defined in Integer Variable on page 6-3.
minutes
specifies an integer, as defined in Integer Variable on page 6-3.
seconds
specifies an integer, as defined in Integer Variable on page 6-3.
fraction
specifies an integer in the range 000 to 999, representing a decimal fraction of a
second.
The only required part of the time specification is seconds. The actual range for the
time value for a particular attribute is context dependent.
Disk File Names
Disk files in the NonStop operating system are identified by a unique, symbolic file
name. VHSCI uses the same conventions. A complete NonStop operating system disk
file name describes the location of a file and has four parts:
•
\system-name
•
$volume-name
•
subvolume-name
•
file-name
For convenience, default values are provided for all parts of a complete file name
except file-name. Default values for a VHSCI session can be established through
the use of the SYSTEM and VOLUME commands. For additional information, refer to
the SYSTEM command and VOLUME command descriptions in Section 7, Command
Descriptions. The initial default values are the values provided by the command
interpreter through which VHSCI was invoked.
File Specification
In the syntax descriptions for VHSCI commands, the variable file-spec is used to
denote a fully or partially qualified NonStop operating system disk file name. A fully
