Hi,

I can't understand why the following code does not work.  Could someone help me out here?

\starttext
\startMPpage
draw textext("\convertnumber{r}{12}");
draw textext("\convertnumber{r}{" & "12" & "}");
\stopMPpage
\stoptext

The first draw statement works perfectly.  But the second one throws out errors and complains as follows:

.....test.tex: ! Missing number, treated as zero


<to be read again> 

 

<argument> \number " 

          & "12" & "

\romannumerals #1->\clf_romannumerals \numexpr #1

                                                 \relax 

<argument> ... draw textext("\convertnumber {r}{" & "12" & "}

                                                  "); 

\meta_process_graphic ...currentMPformat }data {#1

                                                  ;}initializations {\meta_f...

\page_fitting_stop_command ...eter \c!command {#1}

                                                  \page_fitting_stop_normal 


Is there a workaround here?  Ultimately I want to replace "12" with a loop variable in MetaPost.

Thanks,
