Could anyone please explain, why this command has *no* effect:

\def\zweisym#1#2#3#4{
	\startbuffer
\x13	\setupcombinations[width=11cm]
	\startcombination[2]
	{\hbox to 4.75 cm{\hss\externalfigure[#1]\hss}}{#2}
	{\hbox to 4.75 cm{\hss\externalfigure[#3]\hss}}{#4}
	\stopcombination
	\stopbuffer
	\placefigure[][sym:#1-#3]{none}{\getbuffer}
}

\zweisym{pic1}{Text 1}{pic2}{Text 2}

The externalfigures for #1 and #3 are defined before the use of \zweisym

The \def itself is in the header.

Thanks!

Hraban.

Because buffers cannot be used in macro defs that way [parsed while
processing and \stopbuffer is a string them, no \cs. There are some ways to
fill buffers, but that's not needed here.  >\def\zweisym#1#2#3#4{

\def\ZweiSym#1#2#3#4%
  {\placefigure[][sym:#1-#3]{none}
     {\setupcombinations[width=11cm]
      \startcombination[2]
	  {\hbox to 4.75 cm{\hss\externalfigure[#1]\hss}} {#2}
	  {\hbox to 4.75 cm{\hss\externalfigure[#3]\hss}} {#4}
      \stopcombination}}

works. I'm not sure why you set the width.
