These task sequence variables govern the operation of the task sequence action. Variables marked as input variables are read or used by the task sequence action. In most cases, input variables correspond to task sequence action fields in the task sequence editor and can be set via that user interface. Alternatively, input variables can be set at runtime from per-collection or per-computer variables, via the Set Task Sequence Variable action or via the TSEnvironment COM object. Variables marked as output variables are written or set by the task sequence action to be read by later actions in the task sequence.
