It is intended for the use of IBM field engineers, systems analysts and programmers. The ALGOL (F) Compiler is a processing program of the IBM System/360 Operating System. It translates a source module written in the ALGOL language into an object module that can be processed into an executable load module by the Linkage Editor. Page of GY'l3-8000-0 Revised January 15, 1972 By TNL GN33-8129 PREFACE The IBM System/360 Operating System ALGOL handles the output of diagnostic messages Compiler consists of ten phases, or load in the three phases mentioned, is described modules. Chapter 1 of this manual provides in Chapter 9. an introductory survey of the main functions of the several phases. A more Chapter 10 describes the ALGOL Library, detailed description of the individual which consists of a set of load modules phases is provided in the subsequent chap- representing standard I/O procedures, ters, as follows: mathematical functions, and the Fixed Stor- age Area. Directory (IEXOO) Chapter 2 Initialization (IEX10) Chapter 3 Chapter 11 describes the composition of Scan I/II (IEXll) Chapter 4 the object module generated by the Compiler, Identifier Table Manipulation and the organization of the load module at (IEX20) Chapter 5 execution time.
