Summary
This course is designed for those with some knowledge of the COBOL programming language who need to understand the extensions made for IBM's version of ILE COBOL/400. A main focus is Database I/O and the way that COBOL/400 interacts with IBM i DDS (Data Description Specifications) to process externally described database files and internally defined files. Additional Focus is placed on screen display files used for COBOL/400 interactive programming, as it replaces the common CICS programming model.
Prerequisites
Before taking this course, you should have experience in writing COBOL programs. You should also have taken the Programming Introduction to IBM i (iSeries, AS/400) course (PT1301), or have equivalent experience.
