I found the solution to this problem. Have a look into example x12. The
thin bindings of plplot need as strings char_array , but in Ada a '\0'
is not automatically added. You need to do this on you own. You need the
"Interfaces.C" library/module/whatever and than add "& Nul" to the
strings so that they have the correct ending. Maybe Jerry can tell you
how exactly this is supposed to work, or give a better/nicer solution to
this problem.
Regards,
Werner
