Introduction

RPG/400 has proven to be one of the most popular programming languages for application development on the iSeries. This intensive course provides delegates with the skills to develop RPG/400 programs on the iSeries.

What you will learn

On completion of this course, you will be able to:

  • Code, compile and test screen enquiries.
  • Code, compile and test reports.
  • Code arithmetic operations in RPG/400.
  • Use the database in RPG/400 programs.
  • Write a file maintenance program with validation and error handling.
  • Amend existing programs to add further code.
  • Use externally described files in RPG/400.
  • Use structured development techniques.

Who should attend

Applications development staff who will be using RPG/400 to develop or maintain applications written with RPG/400 on the iSeries.

Pre-requisites

iSeries SYSTEM FACILITIES and iSeries PROGRAM DESIGN should be attended prior to this course. The many practical exercises on this RPG/400 course require the delegate to code using PDM, SEU, SDA and DDS, all of which are taught on the iSeries System Facilities course.

Course content

  • Physical and logical file DDS.
  • Field reference file.
  • Level checks.
  • Printer files and printer file DDS.
  • The structure of a report and record formats.
  • Programming on the iSeries (AS/400).
  • RPG specification types and sequence.
  • Fields, constants, indicators and figurative constants.
  • Logic for a report program.
  • Creating a report program.
  • Using structured coding techniques.
  • Accessing the database.
  • Display file DDS.
  • Processing function keys and conditional function keys.
  • Enquiry program logic.
  • Writing an enquiry program with RPG/400.
  • Using arithmetic in RPG/400.
  • Calculation of totals and averages in a report.
  • Use of subroutines to structure programs.
  • Calling other programs and passing parameters.
  • File handling in RPG/400.
  • Partial key processing.
  • Using debug and on-line debug.
  • Data structures and named constants.
  • Introduction to array processing.
  • Using named data areas and the LDA.
  • Reading and updating a data area in RPG/400.
  • Passing parameters with data areas.
  • Concepts and logic of file maintenance.
  • Coding a file maintenance program in RPG/400.
  • File maintenance operations and record locking.
  • Data validation and error messages.
  • Validation routines in RPG/400.
  • Using message files for error messages.

Materials

A course manual with supporting documentation is provided. The course has many practical sessions to allow delegates to develop report and enquiry programs, a file maintenance program, and a load-all subfile program. Delegates will also be amending programs during this course.
