Objects and Object Lists
Objects are the entities that you use the VHSCI to configure, control, and inquire
about. Many VHSCI commands accept a list of object names in place of a single object
name. Listing multiple object names requires a pair of parentheses and commas to
separate each object. Commands are applied to all the objects in an object list. For
example, the commands ASSUME PROCESS, INFO ($VHS, $VHSD), and STATUS
($VHS, $VHSD) apply to both VHS processes: $VHS and $VHSD.
Object-Spec Variable
The variable object-spec is used throughout the command descriptions to represent
all variations of object references.
The general format of object-spec is:
object-type
designates a specific keyword that identifies the type of object referenced or to be
acted upon by the command. In VHSCI, the only valid object type is PROCESS. If
you do not want to retype object-type for each command that requires an
object type, use the ASSUME command to always set object-type to
PROCESS.
object-name
specifies the name of a single object. The general form of object-name is:
$process-name
specifies the name of a process. The process name consists of a dollar sign
($) followed by a letter and by zero to four (zero to three if the node name is
included for network access) alphanumeric characters with no embedded
blanks, for example, $VHSD.
