yes, the thing even odder is that mpsproof is working well.

I mean,  the content between btex ... etex is not pass to TeX(related) procedure

sorry for the strange expression.

Thanks,  The problem may be

====================
%&latex
verbatimtex

...
====================

This one would look the *.mem file mpost required and latex only have
latex.fmt,  thus failed.


====================
verbatimtex
%&latex

...
====================


I changed the order and it seem to work well.

so it suppose to work now.



Thanks all,  the next time i post my problem

I should ,

1. post a minimal instant of the source file
2. error code or error number

am i right?

I'm new to maillist, and  sorry for the ignorance of
*The art of smart question*
