Program Logic
IBM System/360 Operating System
Linkage Editor (E)
Program Logh: Manual
Program Number 360S-ED-510
This publication describes the internal logic of the
15K and 18K versions of the level E linkage editor.
The linkage editor combines and edits modules to
produce a single load module that can be loaded into
main storage by the control program. The linkage
editor operates as a processing program rather than as
a part of the control program.
This program logic manual is directed to the IBM
customer engineer who is responsible for program main-
tenance. It can be used to locate specific areas of
the program, and it enables thE~ reader to relate these
areas to the corresponding program listings. Because
program logic information is not necessary for program
operation and use, distribution of this manual is
restricted to persons wit:h program-maintenance
responsibilities.
