Thanks -

the context way is: \startformula \startalign \NC v \NC = u + at \NR \NC h \NC = ut + \frac12 gt^2 \NR \stopalign \stopformula ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

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. On Tue, Jul 17, 2012 at 07:32:09PM -0400, Matthias Weber wrote:

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.

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.

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. Regards, Khaled
