Rocket AS

The architecture of Rocket AS comprises several key components. The runtime environment is responsible for executing applications written in the 4GL. The 4GL compiler translates the source code into executable instructions.

Client interfaces, including 3270 emulators and Rocket Ascent, provide access to applications. These components communicate using internal protocols optimized for the z/OS and z/VM environments. Data storage is managed through integrations with DB2, VSAM, and sequential files.

The system's configuration involves setting up data source connections, defining user profiles, and configuring system parameters. The CLI is the primary administrative interface, allowing for tasks such as user management, system monitoring, and configuration changes. NET APIs for integration with external systems.

For example, a typical data retrieval operation might involve the 4GL `SELECT` command, which interacts with the database through the runtime environment. Compared to other platforms, Rocket AS offers a specialized environment for mainframe application development, with specific advantages in data access and legacy system integration. The system's design prioritizes performance and efficiency within the z/OS and z/VM environments.
