File No. S360-21 GY28-2021-2 Program Logic Version 8.1 IBM System/360 Time Sharing System Assembler This publication describes the internal logic of the IBM System/360 Time Sharing System (TSS/360) Assembler Program (also referred to as ftthe assembler"). The assembler processes a group of statements written according to the rules of the TSS/360 Assembler Lan- guage into a '1'SS/360 program module. A general explanation of the four phases of language processing in the assembler is provided, followed by individual routine descriptions and flowcharts. A general understanding of TSS/360 and the rules of the TSS/360 Assembler Language is assumed. Prer"equi- site to and co-references with this publication are: IBM System/360 Time Sharing System: Concepts and Faci- lities, and IBM System/360 Time Sharing System: Assembler Language. This publication is intended for use by system pro- grammers involved in changing system code and in alter- ing the assembler design.
