Hi,

whfc uses the following code fragment to specify the number of
pages :

while (fgets(buffer, sizeof(buffer) - 1, fp) != NULL) {
  if (!strncmp(buffer, "%%Page:", 7)) {
    npagecom++;
  }
  else 
    if (sscanf(buffer, "%%%%Pages: %u", &n) == 1) {
      npagecom = n;
      TRACE("Page = %d\n",n);
    }
}
          
it counts either all lines which have a %%Page: or try to get a number
from the %%Pages: tag

In your document you have first a %%Pages: 4 and later for every page
a %%Page, so whfc starts with the npagecom variable preset to 4 and then
count up for every page.  

Seems to be a undocumented feature of WHFC ;-)
