  We read in the Users Guide, AFL Reference Manual, FOR 
  statement"...For loop is extremely flexible. loop-expression can 
  be ANY kind of expression you wish. You can produce not only regular series 
  like this:for( i = 0; i < BarCount; i = i + 3 ) // increment by 3 every 
  iterationbut you can produce exponential series too:for( i = 1; i < 
  BarCount; i = i * 2 ) // produces series of 1, 2, 4, 8, 16, 32, ... ... 
  "
   
  The following loop will produce the Fibonacci series, for 
  any further use.
   
  // The Fibonacci 
  seriesd=2/(sqrt(5)+1);// the accurate calculation 
  of 0.618n=5;for(i=d^(-n);i>=d^n;i=i*d){fib=i;Title=Title+"\n"+WriteVal(fib,1.3);}
   
  The Fib coefficients are accurately calculated and you dont 
  need to write them one by one.
  n may be increased for more Fib pairs.Dimitris
