I would like to create a macro that defines a display formula, and then
redefine the same macro such that the redefinition includes the original
display formula followed by another display formula. Here is my attempt.
\def\foo{\startformula a = b \stopformula} \foo
\edef\foo{\foo \startformula c = d \stopformula} \foo
This fails, and I would appreciate help in getting this to work.
Thanks,
Troy Henderson

Your example works for me when I process it with mkiv but I would use a token list and not a macro to store the content. \starttext % macro \def\foo{\startformula a = b \stopformula} \foo \blank[2*line] \edef\foo{\foo \startformula c = d \stopformula} \foo \blank[2*line] % token list \newtoks\mytoks \appendtoks \startformula a = b \stopformula \to \mytoks \the\mytoks \blank[2*line] \appendtoks \startformula c = d \stopformula \to \mytoks \the\mytoks \stoptext Wolfgang ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 5+ messages in thread

Can values be assigned to tokens directly instead of appending? Obviously one way it to use \newtoks followed by \appendtoks, but once a token has already been defined, can its content be overwritten?
