MODIFY-WORK-TASK-ATTRIBUTE

Modify work task parameters

Function

This statement can be used to specify subsystems which are no longer to use their holder tasks as a work task. It is possible to specify in addition a new TSN which is to be given to the holder task. This statement will be rejected if the specified subsystem does not exist, or if it does not use the holder task as a work task.

MODIFY-WORK-TASK-ATTRIBUTE will be rejected if neither of the following statements has been executed beforehand:

• START-CATALOG-CREATION

• START-CATALOG-MODIFICATION

Format

MODIFY-WORK-TASK-ATTRIBUTE

SUBSYSTEM-NAME = <structured-name 1..8>
,SUBSYSTEM-VERSION = <c-string 3..8> / <text 3..8>
,WORK-TASK = *UNCHANGED (...) / *NO
	*UNCHANGED(...)
		|	TSN = *BY-DSSM / <alphanum-name 1..4>

Operands

SUBSYSTEM-NAME = <structured-name 1..8>
Name of the subsystem which is using the holder task as a work task.

SUBSYSTEM-VERSION = <c-string 3..8> / <text 3..8>
Version of the subsystem which is using the holder task as a work task.
This version must have been declared previously.

WORK-TASK =
Specifies whether the holder task is no longer to be used as a work task, or if the holder task is simply to be given a new TSN.

WORK-TASK = *UNCHANGED
The subsystem is to continue to use the holder task as a work task. However, a new TSN can be issued for the holder task, in the substructure which follows.

TSN =
Specifies the task sequence number (TSN) to be given to the subsystem’s work task.

TSN = *BY-DSSM
Default value: the TSN is issued by DSSM when the work task is loaded.

TSN = <alphanum-name 1..4>
Task sequence number to be given to the work task when it is started.
The specified TSN must be uniquely defined and usable when the subsystem is loaded.

WORK-TASK = *NO
The holder task for the specified subsystem is no longer to be used as a work task.
