Hi,
I have tried the following example (metafun-p.pdf, p. 112-3):
\startMPgraphic
draw unitsquare xscaled 5cm yscaled 1cm withpen pencircle scaled 2mm
withcolor .625red;
\stopMPgraphic
\hbox \bgroup
\loadcurrentMPgraphic{width=5cm,height=1cm}\placeMPgraphic \quad
\loadcurrentMPgraphic{width=8cm,height=1cm}\placeMPgraphic \egroup
but nothing is drawn unless I remove the setups in curly braces (in
which case a rectangle 5cm x 1cm is drawn). Is there a different way to
pass options to the figure inclusion macro?
Interesting....what is happening is something equivalent to
\externalfigure
         [\MPgraphicfile.\the\currentMPgraphic]
         [type=mps,object=no,
          symbol=yes,reset=yes,
          maxwidth=,maxheight=,
          frame=off,background=,
          width=8cm,
          height=1cm]%
and there is no figure. If I remove object=no, the figure is there. I 
do not understand why object=no should affect the placement of the 
figure.

Hi,

right, the object=no value is the problem. You can solve your problem
by inserting the following macro somewhere before starttext in your
document:

\unprotect

  \def\insertMPfileARG#1#2%
    {\ifx\undefined\externalfigure
       \message{[insert file #1 here]}%
     \else
       \externalfigure
         [#1]
         [\c!type=\c!mps,\c!object=\v!yes,
          \c!symbol=\v!yes,\c!reset=\v!yes,
          \c!maxwidth=,\c!maxheight=,
          \c!frame=\v!off,\c!background=,
          #2]%
     \fi}

\protect

I changed only the "no" value from "object" to "yes".
