The Modern RPG IV Language

Overview

This chapter focuses on full-procedural file processing. Full-procedural files are files in which input and output operations to the file are controlled completely by RPG op codes. Contrast that with cycle-bound files where the RPG cycle controls most of the input and output processing. Also remember that the modern RPG language supports several types of file access:

• Primary/secondary processing through the RPG cycle.

• Demand file processing.

• Record address file (ADDROUT) processing.

• Special file processing.

• Pre-runtime table and array processing.

• Embedded SQL file processing.

• Full-procedural processing.
