DESCRIPTION:
Levinson brings his 15 years of experience as an AS/400 programmer/analyst, consultant, and programming teacher at Jefferson College to presenting the essentials of AS/400 subfile programming. . A member of the IBM-sponsored committee that developed the certification test for AS/400 programming, Phil lives in Olivette, Missouri, with his wife and twin sons. Philip J. He holds a bachelor’s degree in Mechanical Engineering from the University of Har
. In addition, the advanced topics help you mine the rich store of data in the file-information and program-status data structures, handle errors, improve data integrity by using journaling and commitment control, and manage program-to-program communication. You learn to design and create subfile records; load, clear, and display subfiles; and create pop-up windows. Essentials of Subfile Programming teaches you to design and program subfiles, offering step-by-step instructions and real-world programming exercises that build from chapter to chapter. From the Publisher Subfiles are the AS/400 tool that lets you display lists of data on the screen for user interaction. An instructor’s manual is

Very practical, real life projects easy to read makes you think on your own, not retype code from the book. I have recommended this book to about six people and all of them loved it. RE to previous review You are probably in the dark about everything that concern computers, try learning DDS first and some basic RPG.
Essentials of Subfile Programming and Advanced Topics in RPG teaches you to design and program subfiles, offering step-by-step instructions and real-world programming exercises that build from chapter to chapter. Three useful appendices cover issues of programming standards and style, testing and debugging programs, and using Screen Design Aid (SDA).. Today programs and systems are increasingly screen-based and interactive. The book will further help you link RPG programs and database files, including using the record format level identifier and the OVRDBF (Override with Database File) and OPNQRYF (Open Query File) comm! ands; mine the rich store of data in the file-information and program-status data structures; handle errors, including using the *PSSR subroutine, the INFSR keyword and LO indicators, error messages, and error logs; improve data integrity by using journaling and commitment control; and manage program-to-program communications, especially via the power of AS/400 data queues. You’ll learn to design and create subfile records; load, clear, and display subfiles; develop display-file code and RPG code for interactive file maintenan
