ALTER Command

The ALTER command changes the values of the attributes of an existing object. This

command changes only the specified attributes of the specified object or objects.

This is a sensitive command.

OUT file-spec

causes any SCF output generated for this command to be directed to the specified

file. The variable file-spec is defined on page 5-9.

object-spec

designates the objects whose attributes are to be altered. The variable object-

spec is defined on page 5-2. You can omit object-spec if it has been assumed.

(See ASSUME Command on page 5-36.) The objects and attributes that can be

altered depend on the subsystem.

SUB [ subobjtype ]

selects the subordinate objects the command affects. The variable subobjtype

can be a subordinate object type or one of the keywords ONLY, ALL, or NONE, as

explained under SCF Subdevices on page 3-5.

LIKE object-name

identifies an object whose attribute values serve as a model for the new values of

the attributes of the object being altered. The variable object-name must specify

an existing object of the same type.

attribute-spec

is a specification of an attribute and a value to be assigned to it. If the LIKE syntax

is used, attribute-spec overrides the setting derived from the LIKE object for

that attribute. The variable attribute-spec is defined on page 5-7.

Consideration

Some subsystems require that attributes be changed only when the object is in a

specific state, such as the STOPPED state for the Kernel subsystem.
