Hi,

The following sample code is working well in the \startMPpage ~ \stopMPpage, but is not working in the \startMPcode ~ \stopMPcode.

The error message is 

\textfont0 is undefined (character 63)

l.6 \setstrut\strut $A$

If I remove “$” from the code, it is also working in \startMPcode ~ \stopMPcode.

Is there anything which I have to set for \startMPcode?

Best regards,

Dalyoung

        offset = 2pt,
        position = point i of p,  
    ];
endfor;
%\stopMPpage
\stopMPcode
