inserting page numbers on huge files

Hi everybody,

I’m evaluating this software because I need to put a page number on huge text files (about 1,5 – 2 GBytes). Page header is clearly detectable and I’ve tried to modify the “putHeader.jsee” macro, but I need to learn more about macro language.
I’ve also searched for such a function in the menu structure and in the macro library. Does anybody know if a similar macro is already available somewhere?

Thanks in advance.
