Bug ?

Hi,

with the code and Metapost 1.204

>8>8>8>8>8>8>8>8>8
verbatimtex
%&latex
\documentclass{article}
\usepackage{fourier}
\begin{document}
etex

beginfig(1);
  label(btex \eurologo etex,(10,10));
endfig;
end
beginfig(2);
  label(btex \textgreek{\euro} etex,(10,10));
endfig;
>8>8>8>8>8>8>8>8

why Metapost search to compile the fig number 2 and make an error
(error who is true because the command \textgreek is unknown)

Greetings,
Christophe Poulain.

If I understand you correctly you want metapost to ignore the
latex error that your input causes? Why would that make sense?

Ah. Because all the btex.. etex label processing for the whole file 
takes place before anything else happens (otherwise each of the labels
would need its own private latex run).

Best wishes,
