Limitation

Good morning,

Concerning the "limitation" problem is attached here a macro which
defines a function from the "Example of a Program to fit non-equidistant
data points".
Note that the "limitation" problem disappears when I define the function
"extern", but this should not be a proper solution... 

I hope You will help me out of this!

A nice day to everybody,

Steve

{

Float_t z[5],x[5],y[5],errorz[5];

//______________________________________________________________________________
void fcn(Int_t &npar, Double_t *gin, Double_t &f, Double_t *par, Int_t iflag)
{
   const Int_t nbins = 5;
   Int_t i;

//calculate chisquare
   Double_t chisq = 0;
   Double_t delta;
   for (i=0;i<nbins; i++) {
     delta  = (z[i]-func(x[i],y[i],par))/errorz[i];
     chisq += delta*delta;
   }
   f = chisq;
}


}
