IBM RPGLE PDF

Overview[ edit ] An RPG program once typically started off with File Specifications, listing all files being written to, read from or updated, followed by Data Definition Specifications containing program elements such as Data Structures and dimensional arrays, much like a "Working-Storage" section of a COBOL program. This is followed by Calculation Specifications, which contain the executable instructions. Output Specifications can follow which can be used to determine the layout of other files or reports. In the early days of RPG, its major strength was known as the program cycle: every RPG program executes within an implied loop , which can apply the program to every record of a file.

The Report Program Generator or RPG for short is a high-level programming language serves a wide array of business applications and uses. Every RPG program executes programs within a hypothetical loop. This loop is able to apply the same program to every file on record. At that time, there will be a comparison between each record and every line in the program. Every line has the choice to either act on the record or not, based on whether that line has an indicator turned on or off.

However, IB has also continued to provide backward compatibility for the cycle. Our programmers create codes that can be integrated into business operations in order to ensure a higher level of efficiency. On any particular day, our RPG programmers generate new cod, maintain and update existing code programs and help you with analysis, design, development and maintenance of your IBMi systems.

They will following various functional specifications in order to create technical documentation and develop pseudo codes, strengthen your existing code or troubleshoot your business processes to diagnose where the issues are. Our programmers can also debug existing software to locate and solve issues. Scale YourDevelopment Team.
