Hi there, I suppose the following fixes your problem though I can not tell for sure, since you did not provide the error message: Replace the stuff connected to \strc_formulas_handle_sub_numbering in cont-new.mkiv with \def\strc_formulas_handle_sub_numbering {\let\strc_formulas_handle_sub_numbering\relax % else error \doiftextelse\currentsubformulasuffix {\strc_counters_setown_sub\v!formula\plustwo\currentsubformulasuffix} {\strc_counters_increment_sub\v!formula\plustwo}% \placecurrentformulanumber} This works for me. I do this every time I update context. Please consult [NTG-context] subformulas: error in latest beta in the mailing list. This is where I reported this bug earlier. Hans himself provided the fix. Hope this helps. Cheers, Andreas Am Oct 14, 2012 um 9:07 PM schrieb Aditya Mahajan:

Hi Aditya,
It seems that numbering subformulas as described in your « My Way » magazine entitled « Using \startalign » does not work with mkiv. The following minimal example taken from page 6 of the above mentioned manual, does not result in what is described there:
\starttext \placesubformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[eq:c][c] \NC a_2 x + b_2 y \NC = c_2 \NR[eq:d][d] \stopalign \stopformula (\in[eq:c]) and (\in[eq:d]) form a linear system of equations. \stoptext
Is this a known bug?
I can confirm the bug. Using \startsubformulas does not work either.
I don't completely understand the new implementation of ConTeXt numbers, so I cannot suggest an immediate fix for this.
