File No. S360-25(Os) Form GY28-6642-4 Program Logic IBM System/3S0 Operating System FORTRAN IV (H) Compiler Program Logic Manual Program Number 360S-PO-500 This publication describes the internal design of the IBM System/360 Operating System FORTRAN IV (H) compiler program. This compiler transforms source modules written in the FORTRAN IV language into object modules that are suitable for input to the linkage editor for subsequent execution on System/360. At the user's option, the compiler optimizes its object modules so that they can be executed with improved efficiency. This manual is directed to IBM customer engineers who are responsible for program maintenance. It can be used to locate specific areas of the program and 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 with program-maintenance responsibilities. Fifth Edition (June 1970) This is a major revision of, and makes obsolete, the previous edition, Form Y28-6642-3. changes to the text, and small changes to illustrations, are indicated by a vertical line to the left of the change; changed or added illustrations are denoted by the symbol
