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.
