Hi Aditya,

I tried to use a buffer but you cannot make something like this:

\starttext

\placefigure
{}
{\startbuffer{mybuffer}
 Floating text from a buffer
 \stopbuffer
 \getbuffer{mybuffer}}

\stoptext

with content saved in a buffer.

It's not a real problem but I wanted to know if it is possible to
define a environment in the way I wanted.
