Progress/400
Product Guide
OS/400 Object Access
The Progress/400 product supports Progress 4GL access to data areas, user spaces, and data queues. AS/400 applications and IBM use these objects and their respective APIs to facilitate interprocess communication, storage of control information, and support of the AS/400 APIs. A Progress-based 4GL application written for the AS/400 can now utilize the same functionality as RPG or COBOL programs.
A Progress 4GL program running on a client or natively on the AS/400 can access these objects through a consistent set of 4GL APIs. A 4GL program that utilizes these APIs can be written for an n-tier configuration, and it will also run on the AS/400 using the Progress/400 Native 4GL Client.
