After you have created an instance of another class, you can access any PUBLIC data member in the class instance. Here is the simplified syntax for accessing a PUBLIC data member of a class:

<ref>:<data-member> 

Suppose you have defined some of the data members of the Emp class to be PUBLIC. For example, the phone numbers, address, and postal code data members for an Emp are defined as PUBLIC because you want to be able access them from the Dept class and from other parts of the application. Here, in the AddEmployee() method of the Dept class, we have created the instance of the Emp class and assigned it to Emp. The PRIVATE data members of the Emp class must be set by calling the Initialize() method of the Emp class. The PUBLIC data members of the Emp class can be set from the Dept class. In this code, we assign values to the Address, Phones, and PostalCode data members of the Emp class instance using the reference to the Emp instance.

method public void AddEmployee 
  (input pEmpNum as integer, input pFirstName as character, 
  input pLastName as character, input pAddress as character, 
  input pPostalCode as character, 
  input pPhones as character extent 3, 
  input pVacationHours as integer, input pJobTitle as character ): 

  var Emp Empl = new Emp (). 
  // call Initialize() method to initialize the private data 
  // members for the Emp Instance  
  assign ttEmployee.FirstName = pFirstName 
    ttEmployee.LastName = pLastName 
    ttEmployee.EmpRef = pEmpl 
    NumEmployees = NumEmployees + 1. 
  return. 
end method.
