  • Bone Up on Free-Form RPG with developerWorks

    January 14, 2014 Alex Woodie

    The new free-form RPG specs delivered with IBM i 7.1 TR7 are the most exciting thing to happen to the language since RPG Open Access was unveiled four years ago. Last week, IBM published a developerWorks guide on how to program within the new free-form method.

    Free-form RPG is intended to move the language away from its fixed-format roots and put it on par with other commonly used languages, such as Visual Basic, Java, and PHP. The idea is to make RPG more enticing to learn, and introduce the language to a new generation of programmers.

    IBM software engineers Scott Hanson and Jing Li put together a 12-page guide to help coders understand how to use the new opcodes for H, F, D and P specs (the C specs were already moved to free form, while the seldom-used I and O specs have yet to be liberated into the free-form realm).

    IBM made several changes to the specifications in concert with the move to free-format coding. The developerWorks article covers the changes for the various specs, with a particular focus on all the changes to the declaration statement (D spec).

    You can download the PDF, titled “Free-form RPG support on IBM i: Overview of recent RPG compiler free-form changes,” at www.ibm.com/developerworks/ibmi/library/i-ibmi-rpg-support/.

    Embrace VS Code for IBM i Development

    The IBM i development landscape is evolving with modern tools that enhance efficiency and collaboration. Ready to make the move to VS Code for IBM i?

    Join us for this webinar where we’ll showcase how VS Code can serve as a powerful editor for native IBM i code and explore the essential extensions that make it possible.

    In this session, you’ll discover:

    • How ARCAD’s integration with VS Code provides deep metadata insights, allowing developers to assess the impact of their changes upfront.
    • The role of Git in enabling seamless collaboration between developers using tools like SEU, RDi, and VS Code.
    • Powerful extensions for code quality, security, impact analysis, smart build, and automated RPG conversion to Free Form.
    • How non-IBM i developers can now contribute to IBM i projects without prior knowledge of its specifics, while ensuring full control over their changes.

    The future of IBM i development is here. Let ARCAD be your guide!
