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.

Error messages

CPF24B4 E

Severe Error while addressing parameter list.

CPF3C17 E

Error occurred with input data parameter.

CPF3C19 E

Error occurred with receiver variable specified.

CPF3CF1 E

Error code parameter not valid.

Note: The Environment Variable APIs provide the getenv() (Get Value of Environment Variable) function necessary to retrieve environment variables in ILE/C. Therefore, programs written in ILE/C do not need to use the QtmhGetEnv() API. This API, for ILE/C, is more difficult to use (and is slower) than the getenv() API on which it is based.

Put Environment Variable (QtmhPutEnv) API

Parameters

Required Parameter Group:

1

Environment string

Input

Char(*)

2

Length of environment string

Input

Binary(4)

3

Error Code

I/O

Char(*)

The QtmhPutEnv API allows you to set or create a job-level environment variable. This is useful for communication between programs running in the same job, such as your program and the Net.Data® language environment DTW_SYSTEM.

Required parameter group

Environment string

INPUT:CHAR(*)

The input string of the form: envVar=value. Where envVaris the name of the new or existing environment variable, and valueis the value you wish to set the environment variable. Note that they are both case sensitive. The server expects this value to be in the CCSID of the job.

Length of environment string

INPUT:BINARY(4)

The input variable that contains the length of the environment string parameter. For example, the length of the environment string envVar=valueis twelve.

Error Code

I/O:CHAR(*)

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.
