Course Description:
This course describes how to process database and printer files in an RPG program. The course begins by discussing how files are described in an OS/400 environment. You will then see how to code the file specification for a database file.
The course then covers the various RPG op codes that are used to process a database file. You will see how to perform basic file operations, such as how to read records (both sequentially and randomly), update a record, delete a record, and add a record to a file. You will also see how to perform more advanced file operations, such as how to set the file position without reading a record, how to use a composite key, and how to release a locked record.
The course then describes the various ways for an RPG program to detect an error condition and the ways to obtain information as to the cause of the error. Next, you will see how to code an RPG program that uses commitment control. The course ends by covering the coding requirements of a program that produces printed output.
