I have two questions:

1. How to define a start-stop command to accept options?

I want to define a start-stop command which can accept options (as \startitemize [packed]), however the \definestartstop does not support this. I found a solution in the list: http://www.ntg.nl/pipermail/ntg- context/2007/025969.html

Unfortunately, when I use \startbuffer in it, context prints "*" in the terminal and waits for input. So it comes to the second question

2. Can \startbuffer be used in other commands?

My code is as following:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \def\startabstract{% \dosingleempty\dostartabstract}

\long\def\dostartabstract[#1]#2\stopabstract{% \startbuffer[#1] #2\stopbuffer}

\let\stopabstract\relax

\def\dostartabstract {\dostartbuffer[abstract][startabstract][stopabstract]}

\startabstract [long] a long abstract \stopabstract

\startabstract [short] a short abstract \stopabstract
