I'm having trouble understanding the '>>' in some Smalltalk programs, Such as this, from Smalltalk By Example:
MyClass>>doThis array := Array new: 3. array at: 1 put: 2.
I can understand that we are creating a new 3-place instance of Array, named array, and putting 2 in the first slot. But I don't understand what MyClass,
, or doThis are doing.
The ">>" is just a way of indicating that you're talking about a message name.
In your example, MyClass is the class name, and doThis is the message name. You'll never actually enter the ">>" when defining a message, instead you'd put the code in the doThis message of MyClass in the browser.
