RE: page n of x

I ran into this problem many years ago. I had a boss who insisted on it. The
most efficient method I found was to generate the report to a disk file,
keeping track of the number of pages. Then I had a generic program which
read the file and dumped it to a spool file, inserting the number of pages
where appropriate. I put a special character in the first byte of the line
where the page number was, so I wouldn't have to scan every line. It worked
well and had the advantage of making reprints easy, as long as the file was
still around. We kept them in a special library and purged them once a
month.

There's no reason to write to a spool file on the first pass. It just adds
extra work when you convert it to a disk file.

You definitely don't want to make two passes against the data.
