Accessing a variable or a function within an object is done using the / (path) notation, which we already encountered as the way to access the elements of a series by index, or using the file-path notation:
square1/length ;== 10square1/display ; Length of square1 is 10
This works the same as the . (dot) notation using the square1.length and square1.display() classes in other languages.
In the same way, you can change data in the object:
square1/length: 5 ;== 5square1/length ;== 5
Another way to do this uses get in or set in to access a field using the literal ' word notation:
get in square1 'length ;== 10set in square1 'length 5 ;== 5
The set word can also be used to initialize all fields to none, or to ...
