using symbols in MetaFun

[Mojca Miklavec <mojca.miklavec.lists@gmail.com>]

Hello,

I have a "conversion" defined in the following way:

\usesymbols[jmn]
\defineconversion
   [gnuplot]
   [$\bullet$,
    $\circ$,
    $\star$,
    x,
    {\symbol[navigation 1][NextJump]}]

I would like to use these symbols in a macro
    draw_symbol(x,y,number)
so that
    draw_symbol(0,0,3)
would draw a star in the origin.

The problem is that I don't know:
- how to use symbol sets inside MetaFun (verbatimtex \usesymbols[jmn]
etex doesn't work here)
- how to enable
    label(btex \convertnumber{gnuplot}{5} etex, (x,y))
  to work properly in metafun (no luck with verbatimtex ... etex again)

Any hints would be appreciated.

Thanks,
    Mojca
