Creating a array of const

How do you create a array that can be passed to Format.  I do not know what the number and type of arguments that need to be passed until run time.
The format string is not an issue, but the argument list is.

Try the following:
procedure TForm1.Button1Click(Sender: TObject);
      Args: array[1..10] of TVarRec;
      FillChar(Args, SizeOf(Args), 0);
      Args[1].VType := vtPChar;
      Args[1].VPChar := PChar('Bob');
      Args[2].VType := vtInteger;
      Args[2].VInteger := 5;
      Caption := Format('%s %d', Args);

Declare the Args array big enough for the maximum number of arguments.  Look up help on TVarRec for the different types.

Hope this helps.
