Audience
This course is well suited to developers who are familiar with programming in any High Level Language (HLL) but new to iSeries RPG IV.
Prerequisites
No prior knowledge of the RPG language is required. However, it is assumed that
delegates will have a programming background in some language, not necessarily
on the IBM i platform.
Delegates should be familiar with the IBM i platform and have practical experience
with the commands and tools relevant to application development and
maintenance.. Though not essential, experience with Rational Developer for i (RDi)
would be an advantage as this tooling will be used throughout the Workshop.
Attendees will require authority to create their own Schemas (Libraries), Tables
(Physical Files), etc. Source scripts will be provided to create a simple database for
subsequent data manipulation.
Attendee's PC's should be fully configured as detailed in a separate Checklist which
can be obtained on request.
Duration
3 Days.
