And is the description I put on the wiki correct? The \grabbufferdata command reads only all text until the end command (e.g. \thisistheend) but the beginning command for the buffer (e.g. thisisthestart) has to be defined by the user. You have to give the name of begin command because context has to know it when buffers are nested (I will a explanation about this in another thread). \starttext \def\thisisthestart {\grabbufferdata[mybuffer][thisisthestart][thisistheend]} \thisisthestart My friend, you would not tell with such high zest To children ardent for some desparate glory, The old Lie: Dulce et decorum est Pro patria mori. \thisistheend \typebuffer[mybuffer] \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 ___________________________________________________________________________________
