1. What's the best way to frame a formula like here:
\placeformula \startformula \mframed{x^2+y^2=z^2} \stopformula
The problem is that:  formula number is shifted downwards in comparison to the formula without a number  I don't know how to do the settings (frame color, frame offset) globally. There's no \setupmframed[...] command. It's probably possible to use a sort of \setupframed[whatever_setting_influencing_only_mframed], but I don't know how.
Sorry, no idea on how to do this.
2. What's the general strategy when doing evel stuff with formula numbering? I would like to use \eqalign and then number formulas like on the following example:
z^2=x^2+y^2 (1) =(x'x_0)^2+(y'y_0)^2 % no number =R^2\cos^2(\phi) (2)
The following works. I still find the amsmath way of doing this much easier, but equation numbering has not been ported to amsl module \starttext \placeformula \startformula \eqalignno{ z^2 &=x^2+y^2 &\formulanumber\cr &=(x'x_0)^2+(y'y_0)^2 & \cr% no number &=R^2\cos^2(\phi) &\formulanumber\cr } \stopformula \stoptext
Can I somehow number the formulas (1), (2), (3.a), (3.b), (3.c), (4), (5.1), (5.2)? I would like to manually provide where to start and stop numbering with x.a or x.1, x.2.
Have a look at the wiki http://wiki.contextgarden.net/Math for the manual way to number each subformula. I think one can define a \start(stop)subformula[format = ??] to put a \place(sub)formula automatically. But I do not know how to define such an environment properly.
3. How can I put more than one equation in a row and number all of them (as if they were placed in three columns)?
One way to cheat can be to start a three column mode \starttext \startcolumns[n=3,tolerance=verytolerant] \placeformula \startformula E = mc^2 \stopformula \column \placeformula \startformula E = mc^2 \stopformula \column \placeformula \startformula E = mc^2 \stopformula \stopcolumns \stoptext Again, one could define a startstop environment for this.
4. How can I move the formula number one row lower in case that the formula is too long and if it would overlap with the formula number otherwise?
Not sure what you mean here. Context (rather tex, I think) does this by default \starttext \placeformula \startformula a = bbbbbbbbbbbbbbbbbbbbbbbb ddddddddddddddddddddddddddd ccccccccccc eeeeeeeeeeeeee fffffffffffffffff ggggggggggggggggggg \stopformula \stoptext HTH, Aditya
