Changing Report OUTPUT parameters at run time (how do you do it?)

How do you handle changing the report OUTPUT parameters at runtime ( PAGE LENGTH, TOP MARGIN, BOTTOM MARGIN, etc. )??? What I'd like to be able to do is to pass it a page length/width into a subroutine and then be able to calculate a reasonable PAGE LENGTH, and MARGINs. This is needed due to the fact that the user is able to specify their own output device (screen, printer, etc) and these could vary in their length/width. Any help would be greatly appreceiated.
