Defining Classes

A Class is defined by a script that may be entered and changed using the editor. A class script may also be constructed from a vector of character vectors, and fixed using ⎕FIX.

A class script begins with a :Class statement and ends with a :EndClass statement.

For example, using the editor:

      )CLEAR
clear ws
      )ED ○Animal

[an edit window opens containing the following skeleton Class script ...]

:Class Animal
:EndClass

[the user edits and fixes the Class script]

      )CLASSES
Animal
      ⎕NC⊂'Animal'
