Did you found anything? I tried to figure out which command in the examples of the wiki work/dont work (I used mkiv stable). So far: \formulanumber -> works in mkii and mkiv \subformulanumber -> works only in mkii \placenamedsubformula -> works only in mkii \placesubformula & \NR[+] -> mkii & mkiv, but (1.name) as number \placeformula & \NR[+] -> works in mkii and mkiv, but (1.name) as number I have a real problem to transform my formula from mkii to mkiv. In mkii I had following: \placesubformulawithnumber[gleichung1] \startformula \startalign[n=3, align={right,middle,left}] \NC PM \xrightarrow{aaa} \NC R_{PM} \NC \xrightarrow{bbb} PM \NR[gleichung1a][.1] \NC R_{PM} \NC = \NC \{ K, F \} \NR[gleichung1b][.2] \stopalign \stopformula Can anyone help me to transform this to mkiv, please? Thanks P.

- can you post your examples (so that they can be added to the test suite) - can you also test this with the current beta

done.. you can find the test file for formulas with mkiv attached to this email. I ran it with the latest beta. A couple of things are working.. but e.g. most ways for subformulas not. The listing is half working.. only the formulas names are missing and the order with the only example with working subformulas is strange. If I made any mkiv mistake please excuse... I tried to figure out / guessed the right mkiv ways. I hope this test files helps you to identify the problem areas. ---------8<------------------- \starttext \title{List of formulas} Strange: Missing name of first formula and strange order of .. 2.a, 2, 2.b... \placelist[formula][criterium=all,alternative=c] \subject{math - formula} This works fine. \placenamedformula[one]{Der einfache Test} \startformula c^2 = a^2 + b^2. \stopformula \subject{math - subformula} This works fine. \startsubformulas[eq:1] \placeformula[eq:first] \startformula PM \xrightarrow R_{PM} \xrightarrow PM \stopformula \placeformula[eq:second] \startformula R_{PM} = \{ K, F, Z, U, I, J\} \stopformula \stopsubformulas \subject{math - align - formula} Works. \placeformula \startformula \startalign[n=3, align={right,middle,left}] \NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[gleichung1a] \NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[gleichung1b] \stopalign \stopformula Also works. \placeformula \startformula \startalign[n=3, align={right,middle,left}] \NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[+] \NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[+] \stopalign \stopformula \subject{math - align - subformula} Does not work: no subformula numbers \placesubformula \startformula \startalign[n=3, align={right,middle,left}] \NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[gleichung1a][.1] \NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[gleichung1b][.2] \stopalign \stopformula Does not work: no subformula numbers \placesubformula \startformula \startalign[n=3, align={right,middle,left}] \NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[gleichung1a][+] \NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[gleichung1b][+] \stopalign \stopformula \subject{math - eqalignno - formula} Taken from wiki and removed the subformulanumber \placeformula \startformula \eqalignno{ c^2 &= a^2 + b^2 &\formulanumber \cr c &= \left(a^2 + b^2\right)^{\vfrac{1}{2}} &\formulanumber\cr a^2 + b^2 &= c^2 &\formulanumber \cr d^2 &= e^2 &\formulanumber \cr} \stopformula \subject{math - eqalignno - subformula} Directly taken form wiki - does not work: subformulanumber is unknown. %\placeformula %\startformula %\eqalignno{ % c^2 &= a^2 + b^2 &\formulanumber{a} \cr % c &= \left(a^2 + b^2\right)^{\vfrac{1}{2}} &\subformulanumber{b}\cr % a^2 + b^2 &= c^2 &\subformulanumber{c} \cr % d^2 &= e^2 &\formulanumber\cr} %\stopformula \stoptext
