Other than using the magic single letter commands, I don't see an easy way of getting a \ in a lua string inside luacode :( - \noexpand\include fails unless I define \include - \letterbackslash include gives "\ include" - \letterbackslash{}include gives "\{}include" Aditya ___________________________________________________________________________________ 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 ___________________________________________________________________________________
