For example, if an application's text messages are all resources, changing the messages to a different language involves just using a different set of resources, rather than recompiling the program. Some resources can refer to other resources. After the program is compiled and linked, another tool builds the necessary data structures from a description of the resources, then attaches those structures to the program file. The program carries the resources on its back like a camper with a backpack full of supplies. It uses a couple of forms, a couple of menus, and a bitmap.
Most programs use many more.
