Hi,

I am trying to learn Metapost using Context. I tried a few examples 
for drawing
things and they worked well. But the show command does not seem to 
work. For

example, the code

\startuseMPgraphic{GridDots}
u=1cm;
pickup pencircle scaled 8pt
for i = 0 upto 2:
for j = 0 upto 2: draw (i*u,j*u); endfor
endfor
\stopuseMPgraphic
\useMPgraphic{GridDots}

from John Hobby's manual works great.

However, the following code gives no output in the PDF file. Am I doing
something wrong?

\startuseMPgraphic{LinearEq}
  a+b = 2a - b = 3;
  show a,b;
\stopuseMPgraphic
\useMPgraphic{LinearEq}

I am using the following version from Texlive
ConTeXt  ver: 2008.05.21 15:21 MKII  fmt: 2008.10.1  int: english/english


The output of show goes to the terminal and the log file. Look for the 
values in filename-mpgraph.log.


\ctxlua{metapost.showlog = true}

Can you make this default?

[NTG-context] Command show in Metapost/Metafun
