ZOOMing in on programming (TI-82)

We all know and love our zoom 4 because of its one decimal per pixel mode.
But what happens when the graph does not fit the screen presented by zoom 4,
that is, if it is larger than -4.7<x<4.7?
At this point I usually tell my students that you can get a "good" window by
setting x and y to a multiple of zoom 4 window. This procedure is wonderful
when you need to get more or less close to the real answer, but it is very
time consuming. So I sat down and wrote a very basic program that would
change my WINDOW to a friendly window of any size that I wish to have.
All you have to do is have the calculator ask how many times bigger or
smaller you want the graph to appear in comparison to zoom 4, then have the
calculator calculate and install the new values into the WINDOW. Done.
This little program is saving me so much time, I love it!
