[NTG-context] lines in \setuptyping

Dear list, I have the following sample: \setuptyping[TEX][lines=yes] \starttext \startTEX code one line before two lines before three lines before \stopTEX \stoptext I thought the lines key should display multiple lines when they are in the code. How should I got the multiple lines in the sample above? Many thanks for your help, Pablo -- http://www.ousia.tk
