File No. 360-25 GY28-2020-2 Program Logic Version B.l IBM System/360 Time Sharing System FORTRAN IV Library Subprograms This publication describes the internal logic of the IBM System/360 Time Sharing System FORTRAN IV mathematical and I/O libraries, including the mathematical, service, and I/O routines. This material is intended for persons involved in program maintenance, and system" programmers who are altering the program design. 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. Program logic information is not necessary for the use and operation of the program. PREFACE This publication is organized into six Appendix A describes those aspects of sections and two appendixes. FORTRAN data management that are unique to the FORTRAN environment. Appendix B is a Section 1 is an introduction to the guide to external names of FORTRAN library FORTRAN mathematical and I/O libraries, routines. including service subprograms, and provides a brief description of their contents and functions. PREREQUISITE PUBLICATIONS Section 2 contains descriptions, in Familiarity with the material contained figure form, of how the library routines in the following publications is essential interact in fulfilling user requests. to the use of this manual: Section 3 describes each mathematical IBM System/360 Time Sharing System: subprogram -- its entry names, function, Concepts and Facilities, GC28-2003 attributes, entry, exit, storage IBM FORTRAN IV, GC28-2007 requirement, error checks, and (where FORTRAN Programmer's Guide, GC28-2025 applicable) accuracy figures. Section 4 describes the service routines REFERENCE PUBLICATIONS residing in the mathematical and I/O libraries -- their subprograms, attributes, Knowledge of the following publications entry names and entry parameters, storage will be helpful in understanding the requirements, error checks, and their concepts and logic of the FORTRAN Library operation.
