Task Attributes

Task attributes describe and control many aspects of process execution. They apply not only to tasks but also to jobs. The same set of task attributes can be used to describe all processes.

The values of the task attributes can be set or interrogated, thus enabling a process to monitor and control the execution of another process or itself. Task attributes are accessed with task variables. Task variables are explicitly declared in a job, and are associated with a particular task by a task initiation statement.

Two predeclared task variables are provided: MYSELF, which accesses the attributes of the task itself, and MYJOB, which accesses the attributes of the job. These are described in MYJOB and MYSELF Predeclared Task Variables.

Task Attribute Groupings lists the task attributes that are available through WFL, with the task attributes grouped together into several functional categories. Task attributes with a type of task or event are not available through WFL, and thus do not appear in the table.

More detailed information on task attributes and their use, including descriptions of all the task attributes, can be found in the Task Attributes Programming Reference Manual.
