Introduction Is Ring some sort of improvement over PHP? List index start from 1 Philosophy behind data types in Ring Search of global names while defining the class attributes The documentation says functional programming is supported, but then this happens? What about predefined parameters or optional parameters in functions? What about the Boolean values in Ring? 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 are the advantages to using Ring over native C or C++? What happens when we create a new object? What is the difference between Ring and Python? And is Ring Open Source? Where can I write a program and execute it? Why I get Calling Function without definition Error? Why I get a strange result when printing nl with lists? Why Ring is largely focussed on UI creation? Why Ring is weakly typed? Why Ring uses 'See', 'Give', 'But' and 'Ok' Keywords? Why do we need Yet Another Programming Language (YAPL)? Why setClickEvent() doesn't see the object methods directly? Why the ability to define your own languages Instead of just handing over the syntax so you can parse it using whatever code you like? Why the window title bar is going outside the screen? Why this example use the GetChar() twice? Why we don't use () after the qApp class name? Why you can specify the number of loops you want to break out of?
