NettetAn overlay-structured program consists of:- A permanently resident portion, called root and A set of overlays. Execution of an overlay-structered program proceedes as follows:- To start with,the root is loaded in the memory and given control for the purpose of execution. Other overlays are loaded as and when necessary. The loading of an … NettetRelocation of Linking Concept • Program relocation is the process of modifying the addresses used in the address sensitive instruction of a program such that the program …
