Thankyou very much for your answers.
Wolfgang, I have the following error when I run that code:
(c:/contextminimal/texmf-context/tex/context/sample/knuth.texerror: ...tminimal/texmf-context/tex/context/base/typo-krn.lua:121: attempt to index local 'before' (a nil value)
I´m using XP
ConTeXt  ver: 2010.01.18 22:43 MKIV  fmt: 2010.1.19  int: english/english
what is wrong?
thankyou for your help.
