5-109

START Command

The START command initiates the operation of an object. Successful completion of

the START command leaves the object either in a STARTED or STARTING state

(unless you specify the SPECIAL option). The use of this command is subsystem-

specific.

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 to be started. The variable object-spec is defined on

page 5-2. If object-spec is omitted, the assumed object is started. (See

ASSUME Command on page 5-36.) The objects that can be started depend on

the subsystem.

SPECIAL

specifies that the object be started and brought into the SERVICING state.

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.

SEL [ NOT ] state

directs the command only at objects in the specified state or only at those not in

the specified state. Valid states are listed in Table 3-1 on page 3-7. The use of this

option is subsystem-specific.

Considerations

•

START might cause downloading of object code into a programmable controller.

•

Some subsystems reply to the command after the start is initiated; others reply

when the start is completed. Refer to the SCF reference manual for a specific

subsystem for details.
