Hi List, is there a way in conTeXt how I can use a filename, so that I can write a text where I can refer to it for using it in the following scenario: I need 4 documents with nearly the same content. what I like to do is to switch in the document depending on the called filename. as I got a file called invoice.tex and create some links to this file called delivery.tex order.tex and so on and now call texexec invoice.tex or texexec order.tex I want the document to recognize in the first case that it is invoice and in the second case that it is order, so that I can use an if then else environment on the different parts where I can define the following if{filename==invoice} then{print this content} else{} if{filename==order} then{print this part of content} else{} Thanks for your help. Greetings Martin
