Duration 4 Days 24 CPD hours This course is intended for This course is the first in a series of two courses designed for programmers who are new to RPG IV. Basic programming experience is required. The student should have attended at least an introductory course to programming such as one of those available at technical colleges. The student is not taught the concepts of programming. Experienced programmers who are new to the Power System with IBM i should also attend this course. Examples of other programming languages are BASIC, COBOL, or RPG II. This course focuses entirely on the features of the RPG IV Version 7 compiler and the techniques that this compiler provides. Features of V7 are discussed. Previous techniques and the maintenance of programs that are written using legacy techniques, such as fixed format calculations, are not covered in the classroom. Some additional material and the bibliography will assist the new RPG IV programmer in the maintenance of legacy applications. Overview Write RPG IV version 7.1 programs to produce reportsWrite simple RPG IV version 7.1 inquiry programs that interact with displaysReview compilation listing, find and correct compilation errorsMaintain existing applications written in the RPG IV Version 7.1 languageUse many popular RPG IV built-in functions This course is a comprehensive exposure to the basic features and functions of RPG IV for Version 7. Course Outline RPG IV introduction Coding specifications for RPG IV Data representation and definition Manipulating data in calculations Using printer and display files in an RPG IV program Structured programming, error handling, subprocedures, and subroutines Using arrays, data structures, and data areas Accessing the DB2 database using RPG IV What's next?
