different style for page numbering

[v.ballantini]

I've already posted this in the writer forum without success, so I decided to post here too.

...I've seen that nobody answered my question ([url]http://www.oooforum.org/forum/viewtopic.php?t=14836 [/url])
, so I try to define it n a other way.

Does someone know how to write a condition to write character "+" if page-number is less than page-count, an write character "-" if page-number is equal to page-count?
I've found that variable PAGE is used for page-count, is there a variable set for page-number? or is it possible to set a variable linked to the page-number?

Thanks a lot.
