F1~e NO. ~3bU/~3/U-31 Order No. GC28-6538-10 OS Systems Reference Library IBM OS Linkage Editor and Loader PrDgram Numbers 36DS-ED-SID 36DS-ED-S21 3SDS-LD-S47 This publication provides the information necessary to use the linkage editor or loader program of the IBM System/360 Operating System to prepare the output of a language translator for execution. The intended audience is a customer applications programmer coding in a higher-level language or a system programmer responsible for installing and maintaining the operating system. An introductory knowledge of the concepts and facilities of .the IBM System/360 Operating Sys~em is required to use this reference guide most effectively. The linkage editor combines and edits modules to produce a single module that can be brought into main storage by program fetch for execution. It operates as a processing program rather than as part of the control program. The linkage editor provides several processing facilities that are either performed automatically or invoked in response to control statements prepared by the programmer. The loader combines the basic editing and loading functions of the linkage editor and program fetch in one job step. It is designed for high-performance loading of modules that do not require the special processing facilities of the linkage editor and fetch, such as overlay. The loader does not produce load modules for program libraries.
