Name of the directive

INPUT; CHAR(*)

The name of the directive to retrieve.

Length of the directive name

INPUT; BINARY(4)

The length of the directive name.

Number of values returned

OUTPUT; BINARY(4)

The number of values returned in the output buffer. This value will be zero if the server finds no matching directives or if there was not enough space available for all the values.

Format name

INPUT; CHAR(8)

The format of the data returned.The possible format names follow:

RTVD0100 Retrieve length/value pairs.

Buffer containing values

OUTPUT; CHAR(*)

The buffer containing the output.

Length of space available

INPUT; BINARY(4)

The length of the space provided to receive the directive values.

Actual length of total values returned

OUTPUT; BINARY(4)

The actual length of the total values returned. When the API is unable to find a matching directive, this value will be set to zero. When the size required for the total value is larger than the length of the space provided, the actual space required for the total number of values is returned.

Error Code

I/O;CHAR(*)

The structure in which to return error information. For the format of the structure and for details on how to process API errors, see the programming topic in the AS/400 Information Center.

Format of Output Data

The buffer will contain data in one of the following formats:

RTVD0100 Format: The server uses the RTVD0100 format to retrieve a list of length and value pairs for the directive specified.

AS/400E specifications

The IBM AS/400E, now more commonly known as IBM i, is a robust and versatile midrange server that has been designed to provide a comprehensive computing solution for businesses of all sizes. First introduced in the late 1980s, the AS/400 series has undergone multiple enhancements and rebranding, with the AS/400E being one of the notable iterations. This powerful platform is closely associated with IBM's commitment to reliability, scalability, and integrated business solutions.

One of the main features of the AS/400E is its highly integrated architecture that combines hardware and software into a cohesive system. This integration allows for seamless operations, reducing the complexity typically associated with managing disparate systems. The system is powered by IBM's proprietary OS/400 operating system, which has evolved into IBM i, featuring advanced capabilities like object-oriented programming, integrated database management, and security features that are essential for enterprise environments.

A key characteristic of the AS/400E is its robust database support, primarily through the use of DB2 for i. This integrated database management system enables efficient data handling and retrieval, facilitating real-time business analytics and reporting. Furthermore, the platform supports a variety of programming languages, including RPG, COBOL, and Java, making it flexible for developers who require diverse tools for application development.

The AS/400E is also known for its exceptional reliability and uptime, making it a preferred choice for critical business applications in industries such as finance, healthcare, and manufacturing. This reliability is backed by advanced error detection and correction mechanisms, as well as redundancy features that help prevent data loss and minimize downtime.

In terms of scalability, the AS/400E can effortlessly expand to accommodate growing business demands. Organizations can increase processing power by adding more resources without significant disruption. This scalability, combined with the system’s built-in virtualization capabilities, allows businesses to optimize resource usage and streamline operations.

Security is another defining feature of the AS/400E. The platform incorporates various layers of security measures, including user authentication, encryption, and comprehensive auditing capabilities, ensuring that sensitive business data is protected against unauthorized access.

Overall, the IBM AS/400E remains a powerful tool in the enterprise computing landscape, providing businesses with an integrated, reliable, and secure solution for their technological needs. Its enduring popularity is a testament to its capability to evolve with changing business requirements while maintaining its core attributes of high performance and stability.
