The message value specifies a new `current working directory' required for the
task. If the value is blank, no change is required; otherwise the change is
made by calling the appropriate system routine.
Whether or not a change was made, the `new' current working directory is
obtained and returned as the message value in final reply message.
CONTROL DEFAULT can therefore be used to enquire the task's current
working directory without changing it.
