6.5. Program Implementation - 3¶
You may have noticed that the
drawDoor procedure do not worry about
where the shape is being drawn. We could put a
goto into them so that they handle
jumping to the right location to draw their shape. But, that would make it so they can
only draw in one location. We will want to call the
drawWindow procedure twice to
draw two different windows. That will not work if
drawWindow always jumps to a fixed
location to do its drawing.
This version of the program has
drawWindow defined. But, it is not tested yet. Add
a test of the procedure to the end of the main part of the program.
