Dear all, I am having problems with subformulas. The following example does not display a subnumber (i.e. I get (1) and (2) instead of (1a) and (1b)): %%%%%%%%%%%%% start example %%%%%%%%%%%% \starttext % from % does not display "subformula numbers"" \placesubformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[+][a] \NC a_2 x + b_2 y \NC = c_2 \NR[+][b] \stopalign \stopformula %%%%%%%%%%%%% stop example %%%%%%%%%%%%% This example is taken from http://dl.contextgarden.net/myway/mathalign.pdf page 6 I am not quite sure for how long this is not working. I have been using the following alternative, which used to work but now gives me an error with the latest beta (ConTeXt ver: 2012.08.16 22:20 MKIV fmt: 2012.8.18): %%%%%%%%%%%%% start example %%%%%%%%%%%% % the following used to work in an earlier version \startsubformulas[eq:ax=b] \placeformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[+][a] \NC a_2 x + b_2 y \NC = c_2 \NR[+][b] \stopalign \stopformula \stoptext %%%%%%%%%%%%% stop example %%%%%%%%%%%%% Any suggestions?
