You can’t do this form a definition for a verbatim command because TeX has its own rules for such a situation (search for a description about catcodes), when you want a copy of \TeXcode add

\definetype[arg][TeXcode]

to your document.

BTW: \arg is a predefined command and you should avoid to redefine it

Many thanks for your reply, Wolfgang. Is there no way that I have the already predefined \arg with colored contents (braces included)? Even with defining another command, the problem is that left and right aren’t covered by option=TEX. Many thanks for your help, Pablo -- http://www.ousia.tk

Dear list,

I have the following sample:

\definetype[TeXcode][option=TEX] \def\arg#1{\TeXcode{{#1}}} \starttext \arg{\em\de Textsatzsystem}

\TeXcode{{\em\de Textsatzsystem}} \stoptext

I don’t know what is wrong defined in \arg that inserts an extra space after \em?

You can see how TeX works with \tracingmacros \definetype[TeXcode][option=TEX] \def\arg#1{\edef\temp{#1}\TeXcode{{#1}}} \starttext \tracingmacros1 \arg{\em\de Textsatzsystem} \tracingnone \tracingmacros1 \TeXcode{{\em\de Textsatzsystem}} \tracingnone \stoptext

Many thanks for your reply, Luigi. Sorry, but I have just downloaded and read your message. Well, this seems to be something beyond my understanding (this is all Greek to me). The only conclusion I can draw is that I have to use the second option. Many thanks for your help, Pablo -- http://www.ousia.tk
