I would like to see Hans's suggestion explored a little more, in the following directions: 1. If I never use \pageref in my document, the speedup of `syntax-only' typesetting on the first pass might be very welcome. (I.e., putting the entire document contents into the separate file.) 2. If all my cross-references are backward references, I would like to get my final dvi file after the first pass! 3. If the bibliography data is processed at the very beginning of a document in a sort of `numbers-only mode', then all \cite commands also could be back-references and I could get my final dvi file in one pass. 4. The texinfo idea of processing the table of contents at the end of the document would be nice (let the reordering of pages happen at the DVI driver level, if necessary; for that matter there is a sensible Russian convention to put the TOC at the end of a book anyway). Then maybe even the TOC, with correct page numbers, can also be gotten in one pass!! (Add exclamation points according to taste :-) (Hmm, I think I see a low-tech way to make a lot of this work even more simply, come to think of it ... ) Michael Downes, [log in to unmask] ```
