\startMPcode and \startMPpage

\startMPcode and \startMPpage

[-- Attachment #1.1: Type: text/plain, Size: 991 bytes --]

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

\starttext ... \stoptext

or

\startMPpage[instance=doublefun]

\stopMPpage

Dear Hans,

Thank you for the reply.
Since  \startMPcode … \stopMPcode form is used in the manual, I think that it is OK to use it for all cases.

Thank you again.

Best regards,

Dalyoung
