If you tried out the examples at the start of this section, you may be
wondering what happened about the output parameters for STATS. The
STATS application writes the various statistics it
calculates to lots of output parameters, which can be used by subsequent
applications. If an application is re-run several times to process
different data files then the values left in the application's output
parameters will be the values created on the last invocation of the
application.
