[NTG-context] two questions on mail merging

Dear list, I have the following sample kindly provided to me by Jaroslav: \unexpanded\def\lineaction{ \Name\crlf \Address\crlf \Postcode--\City\crlf \page } Well, how can I put this (or a similar) structure inside a layer? A minimal layer would be: \definelayer[MyLayer][state=start] \setlayerframed[MyLayer][frame=off]{merge fields} \setupbackgrounds[page][background={MyLayer}] \starttext a \stoptext Many thanks for your help, Pablo -- http://www.ousia.tk
