Dynamically call a function

[salvomic]

hi,
I want call a function dynamically, i.e. nameplanet() to call Mercurius(), Saturnus()... giving a variable: nameplanet (:= "Mercuriius" ...)

This code doesn't work:

Code:


  CASE // call constants for planet
  IF nameplanet:="Mercurius" THEN Mercurius(); BREAK; END;
  IF nameplanet:="Venus" THEN Venus();BREAK; END;
  IF nameplanet:="Mars" THEN Mars(); BREAK;END;
  IF nameplanet:="Jupiter" THEN Jupiter(); BREAK; END;
  IF nameplanet:="Saturn" THEN Saturn(); BREAK; END;
  IF nameplanet:="Uranus" THEN Uranus(); BREAK; END;
  IF nameplanet:="Neptunus" THEN Neptunus();BREAK;  END;
  IF nameplanet:="Pluto" THEN Pluto(); BREAK; END;
  DEFAULT data();
  END; // case

It gives "Bad argument type" in my program...

Any hint?

Thanks
Salvo
