Opnqryf by Example

by Mike Dawson

The OPNQRYF command is the single most dynamic versatile command on the AS/400 and probably the least understood. This book takes programmers through the details of this command with lots of examples for a quick increase in productivity. The examples are drawn from real-life, real-job experiences. Among the topics selecting records with the QRYSLT keyword, ordering data with the KEYFLD keyword, building dynamic selection expressions, replacing joined-logical files with OPNQRYF, and much more.
