Look up fit in the Help Browser. You will be taken to a page of specifications on Fit. At the bottom of that page is a section that has Further Examples. I was about to make up an example when I realized that this section has several that are virtually identical to one that I would make up (i.e. I think that they are pretty clear). If you have specific questions after looking at the examples, write again.
