Hello, For a publication I need to typeset a lot of math formulas. To make them as comprehensible as possible, I need a few specialties, and would appreciate any suggestions you can provide: 1) Some of the formulas should be numbered, some not; and at the same time I would like to align several of them. For alignment I seem to be able to use \eqalign (or \startalign ... \stopalign from the t-amsl.tex sent around here lately). But if I place a \placeformula in front of this, the whole aligned block only gets one number; I would need a number for every line (or even better: a possibility to state, which lines should be numbered, and which not). By looking into core-mat.tex I found the commands \formulanumber and \subformulanumber which I can add after each line, if I want it to be numbered. Unfortunately they only set numbers, if the whole aligned block also is numbered (by using \placeformula), and they furthermore do not put the number beside the right margin, as is done by \placeformula, but directly where the \formulanumber appears. How can I enable the numbers even when not using \placeformula (or when using \placeformula[-]), and how can it put the numbers next to the right margin? 2) What are the keywords "alternative" and "indentnext" in \setupformulae meant for? Is there any documentation available concerning math formulae, besides "ConTeXt, the manual"? 3) I'd like to be able to set more than one line below large math operators, e.g. something like \sum_{m: \\ 1 \leq m \leq M}. Unfortunately this does not work as expected (it seems to conflict with the \startalign block). Is there another possibility? 4) Using the alignment features (\eqalign or \startalign, \stopalign) I often have the problem, that the (quite space consuming) formulas all appear on the next page, separated from its introductory text. I would like to have either also the introductory text put onto the next page (but neither \page[no] between text and formulas, nor \page[preference] before the introductory text work), or alternatively, to be able to (automatically) break the formulas inside the alignment block (whether alignment is kept up or not between pages does not matter for me). Is there a solution for either way?
