Sets how PAGE will end each page.
Normally, when PAGE reaches the end of a
page, it sends a form feed character (which is a command to the printer to advance
to the top of the next page. This saves time
and/or space (if the output is sent to a
file), and normally works fine since most
printers automatically keep track of where
the top of the page is and default to a 66
line page. By turning formfeeds off with
.FF0, PAGE will not send formfeed characters,
but send the correct number of line feed
characters to the printer to advance to the
next page. This is desirable when using an
odd sized form which would not correspond to
the printers calculation of the top of the
form.
