The task sequence variables govern how the task sequence action operates. The task sequence action reads and uses the variables that you mark as input variables. Alternatively, you can use the Set Task Sequence Variable action or the TSEnvironment COM object to set the variables at runtime. Only the task sequence action marks variables as output variables, which are read by actions that occur later in the task sequence.
