  • If the IBM i is a business computing engine, CL is the "gears" that let you put the engine to work. CL, the IBM i's control language enables IBM i users to access thousands of system functions, from powering the system up or down to configuring the system to running programs ... and so much more.

    IBM i professionals have long relied on the practical, expert guidance in Complete CL to help them get the most from this powerful and flexible language. In this Sixth Edition, author Ted Holt has revised the book to bring it current with the latest version of CL and modern IBM i usage. Holt, recognized CL authority, explains CL programming clearly and logically, taking you through each CL component. With Complete CL: Sixth Edition, you'll have all you need to know to build robust production-grade CL programs that let you run your IBM i "engine" with confidence.

    • New built-in functions for string handling, case conversion, data-type conversion, and data validation
    • New commands and updates to commands
    • New support for SQL

    Plus, you will develop the skills needed to:

    • Write robust, production-grade programs in IBM i CL
    • Compile CL programs and modules, and combine modules into programs
    • Handle unexpected errors in a graceful manner
    • Use powerful built-in functions with character and numeric data
    • Use looping and decision structures
