The basic TeX structure for this would be an full-width \eqalignno, like so: \def\fixeqline{\noalign{\kern-.4\baselineskip}} \def\guessedstrut{\vrule height 12pt depth 12pt width0pt} $$\eqalignno{ & 15, \hbox{ if something} & (1)\cr \fixeqline x=\smash{\left\{\guessedstrut\right .} & & \cr \fixeqline & 0, \hbox{ otherwise} & (2)\cr} $$ Not very nice, but TeX (the engine) does not allow a cleaner solution. I guess it is possible to wrap this up in a nicer looking macro, but it requires some trial typesetting for the magical quantities used in the two macros. Cheers, Taco
