Introduction

This course is intended for RPG programmers either coding with RPGLE or RPG methods developing applications
and a follow on course to the Introduction to Subfile Programming (ISRPS).

What you will learn

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

  • Flexible data loading with Expanding (page by page) Subfile programming techniques.
  • Volatile data control with Single page Subfile programming techniques
  • Coding page control & Refresh options within RPG
  • Plus sign control for advanced coding techniques.
  • Data Entry Subfile coding techniques.
  • Common methods for Subfile and Subfile control validation.
  • Error message Subfile definition.
  • Adding, Removing and Displaying messages with an error message Subfile.
  • Introduction to Embedded SQL & Bindable techniques with Subfiles.

Who should attend

RPGIV or RPG/400 programmers developing and maintaining subfile applications.

Pre-requisites

A basic understanding of RPG programming and Load All Subfile programming techniques as covered in the RPG programming and Introduction to Subfile Programming courses.
.

    Error message Subfiles
  • Explain what an error message Subfile is used for
  • Code an error message Subfile
  • Remove messages from an error message Subfile
  • Display messages from the Subfile via RPG

    Modular Subfile Techniques
