That should be:
COND_STYLE1

If document1 has more than one page, use style2, else
If document has more than 2 pages, use style3, else
use style4
use style1

No, sorry. I'm assuming there's an implied exit from COND_STYLE1 with
each "use" (or style1 would always be used) -- but even so, this will
have the following result:
* For a one-page document, use style4.
* For a two-page document, use style2..
* For a three or more page document, use style2.
I think what you're after is to use style1 for a one-page document,
style2 for a two-page document, and probably style3 for a three-page and
style4 for more than three pages -- right? Perhaps you're sure the
documents will never be more than four pages, and that each of your
"stylen" definitions is actually a set of page styles, with each
specifying the name of the next page style in its own set. Let's call
the possible page styles Page1, Page2, Page3, and FinalPage. A one-page
document should use FinalPage, a two-page document would start with
Page1, which flows to FinalPage. A three-page document would start with
Page1, which flows to Page2, which flows to FinalPage. A four-page
document would start with Page1, which flows to Page2, which flows to
Page3, which flows to FinalPage. More than four pages would use
FinalPage for the fourth page, but I'm not sure what would happen then.
All but FinalPage have the simpler footer and probably no other
differentiation. So assuming that case is not possible, your conditional
statements could be expressed like this:
COND_STYLE1
{
If document1 has more than 3 pages, use style4, else
If document has more than 2 pages, use style3, else
If document has more than 1 page, use style2, else use style1
}
All this is a very cumbersome mechanism; I showed one that needs one
condition (is this the last page?) and two page styles (I used Default
and Final Page) that accomplishes the same thing and can handle any
number of pages. That one seems as if it might have a reason to exist,
but I see no particular reason for anything that introduces these new
mechanisms (naming page style sets, either using no page styles at all
until the final document length is known or overriding whatever was
used, and providing the conditional logic structure with its implied exit).
If I'm misunderstanding what you're after, please explain further.
