AUDIENCE:   Programmers responsible for writing and/or maintaining RPG IV code. Part one is designed for programmers new to RPG. Part two may be attended by programmers with some experience of RPG IV who need to learn about more advanced features in RPG IV. PREREQUISITES:   Before taking this course, a student should: - Have a basic knowledge of the development environment (WDSC/RSE/Rdi or PDM/SEU) available through i for Application Developers and/or WDSC/RSE/RDi for Programmers. - Know about the concepts of externally described files (i.e. DDS or SQL) available through i for Application Developers. - Be familiar with the system facilities (menus, CL commands, jobs, etc) available through i for Application Developers. - Have a basic knowledge of programming (sequence, loops, subroutines etc.) DURATION:   5 days. Hands on. OBJECTIVES:   On completion of the course, participants should be able to code and debug simple RPGIV programs, both interactive and batch. Specifically the student will understand: - How data is stored and manipulated by RPG - RPGIV...coding structure, indicators, operation codes, etc. - Record retrieval operations - Workstation and printer file handling - Tables and arrays - Program calling and parameter passing. - Structured programming techniques. - Data structures and data areas. - Multiple occurrence data structures. - Subfiles. - Error Handling. - Debugging.
