The \NR before \stopmathcases is missin=

OK. Though I know it, it is hard to get used to, coming from LaTeX.

But the spacing is wrong: too much between the two components. These are =
not cases, but aligned formulas: one might have a number of alignments, n=

Take a look at my previous example wher=
e I changed the distance between both columns with the distance key.


I missed that. It fixes the spaces within the formula, but adds space bet=
ween the two sets relative both TeX and AMS-LaTeX (which has about the sa=
me as TeX), cf. example below.

In AMS-LaTeX one can have more than one alignment, though when trying it =
between the =E2=80=9C-=E2=80=9C and the =E2=80=9C=CF=89=E2=80=9D in the s=
econd (right-most) set, it adds a lot of space, rather than just trying t=
o align a compactly as possible. In ConTeXt, nothing happens with extra a=
lignments; in TeX, there is an error.

So using \startmathcases is a workaround: trying to force it to do someth=
ing it wasn=E2=80=99t intended for.
You can set the alignment for each column in a matrix with the align=20 key.
