Y28-660l-2 Program Logic IBM System/360 Operating System FORTRAN IV (E) Program Logic Manual Program Number 360S-FO-OS2 This publication describes the internal design of the IBM system/360 Operating System FORTRAN IV (E) compiler program. Program Logic Manuals are intended for use by IBM customer engineers involved in pro- gram maintenance, and by system programmers involved in altering the program design. Program logic information is not necessary for program operation and use: therefore, distribution of this manual is limited to persons with program maintenance or modi- fication responsibilities. Restricted Distribution PREFACE This manual is organized into three Although not prerequisite, the following sections. Section 1 is an introduction and documents are related to this publication: describes the overall structure of the compiler and its relationship to the oper- ating system. Section 2 discusses the IBM Systern/360 Operating System: FORTRAN functions and logic of each phase of the IV (E) Library Subprograms, Form compiler. section 3 includes a series of C28-6596 flowcharts that show the relationship among the routines of each phase.
