File No. S360-25 Form GY28-6831-2 Program LogiC IBM System/360 Operating System FORTRAN IV Syntax Checker Program Number: 360S-PO-550 This publication describes the internal logic of the FORTRAN IV Syntax Checker, which is a component of the IBM System/360 Operating System Conversational Remote Job Entry (CRJE) and of the Time Sharing option (TSO) of System/360 Operating System. Thus, the reader is required to have a knowledge of FORTRAN IV and an understanding of the concepts and facilities of CRJE and/or TSO. The publication identifies areas of the syntax checker that perform specific functions and relates those areas to the program listings. The FORTRAN IV Syntax Checker, a processing program called via the terminal command language of CRJE or TSO scans input written for the E, G, Gl, H, or Code and Go levels of the FORTRAN. l;V language for syntactical errors. The input is checked on a single-statement basis, i. e., no cross-checking between statements is performed. The syntax checker:
