 For more examples of using registered variables in conditions on later tasks, see :ref:`playbooks_conditionals`. Registered variables may be simple variables, list variables, dictionary variables, or complex nested data structures. The documentation for each module includes a ``RETURN`` section describing the return values for that module. To see the values for a particular task, run your playbook with ``-v``.

+Registered variables are stored in memory. You cannot cache registered variables for use in future playbook runs. Registered variables are only valid on the host for the rest of the current playbook run, including subsequent plays within the same playbook run.
 
 Registered variables are host-level variables. When you register a variable in a task with a loop, the registered variable contains a value for each item in the loop. The data structure placed in the variable during the loop will contain a ``results`` attribute, that is a list of all responses from the module. For a more in-depth example of how this works, see the :ref:`playbooks_loops` section on using register with a loop.
