John,

You could add a property to the CustomerInteface class and assign an instance of the DataManager to this property. Try something like this:

DEFINE CLASS CustomerInterface AS SESSION OLEPUBLIC
  *-- object reference
  oDataMgr = NULL

  PROCEDURE Init
    *-- instantiate DataManager
    This.oDataMgr = CREATEOBJECT("DataManager.DataManager")
  ENDPROC

ENDDEFINE

You can now access public methods and properties of the DataManager with the following syntax:

oCust = CREATEOBJECT("customerInterface.Customer")
oCust.oDataMgr.AnyPublicMethod()
?oCust.oDataMgr.AnyPublicProperty

2. Put your code between < PRE > and < /PRE > tags (without the spaces)
