  17. COMMENTS
  18.  
  19.     The syntax 'xxxx' results in four characters packed into a short int. This is
  20.     a Macintosh convention, not Standard C. That's ok since this routine is strictly
  21.     Macintosh anyway.
  22.  
  23. EXAMPLE
  24.  
  25.     ** create Cricket data file **

  28.     fprintf(myFile,"*\n");
  29.     fprintf(myFile,"x\ty\n");
  30.     for(i=0;i<n;i++)fprintf(myFile,"%9g\t%9g\n",x[i],y[i]);
