iSeries (AS/400) Crossover to Modern RPGLE code

Introduction

This course updates RPG programmer's skille to utilise modern RPGLE programming techniques, introducing features of the programming language such as FREE FORMAT code. Built In Functions, true date fields and pointers, sub-procedure coding and debug tools.

Who should attend

Programmers who are proficient in writing RPG/400 programs on the iSeries and who want to become more productive with the new features of RPGLE.

Pre-requisites

It is expected that delegates attending this course are already proficient in RPG, either through attending an RPG/400 Programming course or having gained the equivalent practical experience, at least 6 months real experience of coding RPG/400 or earlier, fixed format code.

Course Overview

Materials

A course manual with supporting documentation is provided. The course includes a series of practical sessions to initially convert an RPG/400 program to RPGIV, and then to update the coding within the program to use RPGLE coding techniques and practices.
