I should follow my own advice! As the TeXbook points out, Plain TeX has a perfectly good \cases command which is also present in ConTeXt, and which you use like this:P_{r-j} = \cases{ 0 & if $r-j$ is odd,\cr r!(-1)^{(r-j)/2} & if $r-j$ is even.\cr }Note that, in this version, the text in the second column is _not_ enclosed in a \text command; the \cases command handles that automatically.
Thank you very much. This is just what I need. jk -- // Jilani KHALDI http://jkhaldi.oltrelinux.com _______________________________________________ ntg-context mailing list [email protected] http://www.ntg.nl/mailman/listinfo/ntg-context
