Fibonacci numbers in Wolfram Mathematica

Example for versions Mathics 0.5, Wolfram Mathematica 8.0.4

Print always outputs a newline after the output, so to prints the numbers in a single line, one has to accumulate them into a string and print it. <> is concatenation operator, it works only on strings, so the result of Fibonacci call must be converted to string explicitly using ToString function. 

msg = "";
Do[msg = msg <> ToString[Fibonacci[i]] <> ", " , {i, 16} ];
Print[msg, "..."];
