Class declarations

A class is created in a manner similar to a structure, using the DEFINE command.

A simple class declaration has the form:

DEFINE CLASS new_class_name
  field1_type field1_name
  field2_type field2_name
  ...
ENDDEFINE

For example, the following declaration creates a class called Circle:

DEFINE CLASS Circle
  double CenterX
  double CenterY
  double Radius
  double Area
ENDDEFINE

Once the class has been declared, objects of the class can be declared using the LOCAL and GLOBAL commands. This has the general form:

local class_name obj_name

Example:

local Circle c
c.CenterX = 5
c.CenterY = 3
c.Radius = 2
c.Area = 12.57

The declaration of class methods is separate from the class declaration and is described in Member functions.
