2.18 Referencing

You can use references to:

• Dynamically create and destroy components. In this way you can control the life span of components and  the memory use of your application. For information, refer to Dynamic Multi-Form Application.

• Pass values between components. Referencing is the most efficient way of communicating between components.

• Communicate with ActiveX (COM) components. For details, refer to ActiveX Controls.

References are set and used in:

• The REFERENCE parameter of the DEFINE_COM command

• The SET_REF command

• The IF_REF command

• In the PASS *BY_REFERENCE parameter of the DEFINE_MAP command
