This session shows how a service program that was originally used for a 5250 application can be used to create a web-service. In this presentation, we will work through the steps required to make a number of web-services using a service program, install the web-services on the IBM Integrated Web Services Server and consume the web service using PHP and Java.

This session demonstrates the use of SQL in your programs. After a short discussion of the differences between Dynamic and Static SQL in your programs; we demonstrate the important concepts in creating a robust SQL program.

This session discusses the advantages of using modern techniques in your RPG programs. After a short introduction to modularity in programming; we go step-by-step through the process of replacing called programs with sub-procedure modules and then converting these modules to procedures in a called service program.

This combined lecture and lab will show the attendee how to take a traditional subfile program and convert the disk I/O to SQL then move this database I/O to a service program. This decoupling of the UI (5250 Subfile) allows the service program to be used as a web service. The session will take the attendee through the process of developing a SQL/Service program based CRUD application using Free Form RPG and RDi’s (Remote Systems Explorer and Screen Designer).
