Almost similar as to provide "Page 1 of 100", "Page 2 of 100". This seems to 
be tricky enough. AFAIK, 1.19 version of RL does not really knows how much pages 
it will produce. Maybe newest knows already, but I am not aware of this.

However, at least one (ugly) workaround still exists:

  1. Leave empty place, like: "Pages 1 of      ".
  2. Process document and count the pages.
  3. Process document AGAIN and write these numbers on that place in the forms.

Caveat: if you want right-justified or centered text, you may fail aligning it 
properly, since you don't know exact width of the currently placed text. One 
more workaround for this is to process the document three times: first, you
know how much pages, second, you know the width of the text for each page
and finally you paint this stuff properly. :-)

Although I am really intersted what Robin would reply on this...
