Description

The visibility of the properties of an object is governed by their scope. The default visibility is public, but this can be changed by using one of the scoping commands. Once the scope is changed, it remains in effect on all property and method definitions that follow, until it is changed again or the ENDCLASS command is reached.

Scope	Description
LOCAL	Local properties and methods are visible only to the object where they are defined.
PRIVATE	Private properties and methods are visible only to the object where they are defined and to all methods and properties of objects called by the object.
PUBLIC	Public properties and methods are visible everywhere.
STATIC	Static property values are shared by all objects of the same class.

Example

// Use of Scope Options
class myclass 
    public:
        property cPUBLIC_PROPERTY
        method Show  && Publicly available method
            //...
        return  && Show
    private:
        property cPRIVATE_PROPERTY
    local:
        property cLOCAL_PROPERTY
    static:
        property cSTATIC_PROPERTY
