Then I realized that it is not 1.4ex but 1.4\ex@ with \ex@ as .2326ex. ughh....the ugly syntax of plain tex... So here is a more reliable reproduction of amstex dddot and ddddot \newdimen\amstexex \amstexex = .2326ex \def\dotsadjustbox#1% {\vbox to -1.4\amstexex{\kern-2\amstexex \hbox{\the\textfont\zerocount#1}\vss}} \def\dddot#1% {{\mathop{#1}\limits^{\dotsadjustbox{...}}}} \def\ddddot#1% {{\mathop{#1}\limits^{\dotsadjustbox{....}}}} \starttext $\dddot{a}_{\dddot{b}}$ $\ddddot{a}_{\ddddot{b}}$ \stoptext Hans, can these definitions be added to the core?
