Hi,

In essence the following example, based on the result of some processing
saves output to one folder or another.  In doing so I repeat all the store
and result code twice.

I'm wondering if someone could show me how to take the store and result code
and put it into one step that gets called from two places passing as
parameters the output folder and file name.
