[NTG-context] toc and macro

[Harry]

Hi,

I hope that this is the right address to post my question. If not I
would be glad for a tip.

I wanted to do something like this:

_______________________

\unprotect

%This line uncommented leads to an error
\def\tit{Oops!}

\def\Teil{\dodoubleempty\doTeil}
\def\doTeil[#1][#2]#3{%
  \def\tit{#1}
%...
  \startchapter[title={\tit},reference={#2}]
    #3
  \stopchapter
%...
}


\protect

\starttext

  \completecontent

  \doTeil[Hallo][hallo]{Text Text Text Text Text Text Text}

\stoptext

_______________________

It works if i use #1 direct (like this):
  \startchapter[title=#1,reference={#2}]
But how can I wrap it in the \tit?
(wrapping #2 works fine)

I wanted to programm \doTeil so, that I can nest it freely (for example
with \input) and the table of content uses the hierarchy of the nesting
to produce a nice TOC.

thanks for help.

Sincerely, Harry
