What about Data Representation in Ring? What about Memory Management in Ring? What about predefined parameters or optional parameters in functions? What about the Boolean values in Ring? What are the advantages of using Ring over native C or C++? What are the advantages to using Ring over C# or Java? What are the advantages to using Ring over Lisp or Smalltalk? What are the advantages to using Ring over Python and Ruby? What are the advantages to using Ring over Tcl and Lua? What happens when we create a new object? What is the difference between Ring and Python? And is Ring Open Source? What is the Ring Architecture? Where can I write a program and execute it?

Why I get Calling Function without definition Error? Why is Ring largely focused on UI creation? Why is Ring weakly typed? Why Ring is not case-sensitive Why Ring uses 'See', 'Give', 'But' and 'Ok' Keywords? Why setClickEvent() doesn't see the object methods directly? Why the ability to define your own languages Instead of parsing? Why the Assignment operator uses Deep copy? Why the window title bar is going outside the screen?
