Tasks property of the job contains four task objects. The first task in the job's Tasks
property corresponds to the task run by the lab whose labindex is 1, and so on, so that
the ID property for the task object and labindex for the lab that ran that task have the
same value. Therefore, the sequence of results returned by the getAllOutputArguments
function corresponds to the value of labindex and to the order of tasks in the job's
Tasks property.
Compatibility Considerations
In past releases, there was no correlation between labindex and the task ID property.
