the context way is:

\startformula \startalign
  \NC v \NC = u + at \NR
  \NC h \NC = ut + \frac12 gt^2 \NR
\stopalign \stopformula

Thanks - I wasn't aware that the human readable version had been deprecated :(

The use of & (which is a common symbol) as a control character is a long
standing idiosyncrasy of TeX that I'm glad ConTeXt has got rid of.

It was never a problem in TeX to modify the control characters used according to your own pleasure. For me, the problem is now to change the 200+ occurrences of start/stopaligns distributed over dozens of files to the politically correct syntax.

Re: Is startalign broken in mkiv?

[Rogers, Michael K]

Here's a backward-compatibility hack that works on your minimal example.  Maybe it will save the dozens of files without changing all the &s:

\let\oldstartalign=\startalign
\let\oldstopalign=\stopalign
\let\oldbs=\\
\def\startalign{\catcode`&=4\let\\=\cr\oldstartalign}
\def\stopalign{\oldstopalign\catcode`&=12\let\\=\oldbs}
\starttext
This \& that & the other thing:
\startformula \startalign
v &= u + at \\
h &= ut + \frac12 gt^2 \\
\stopalign \stopformula
That \& this & yet another thing.
\stoptext

Hope that helps.

Michael

Except that is not the kind of thing ConTeXt users are supposed to mess
with, I feel guilty every time I mess with catcodes in my style file.
