Cause . . . . . :

The field, subfield, TAG, data

 

 

 

structure, PLIST,

KLIST, subroutine, indicator,

prototype is defined in the program, but not referenced.

Externally-Described file is not u￿sed.

 

Cause . . . . . :

There is a Record-Format name

for an

 

 

Externally-Described File that is not used on a

valid

 

 

input or output operation.

 

 

Recovery

. . . :

Use the Record-Format name of

the

the name as a parameter for keyword IGNORE. Compile

 

 

again.

only w￿hen

 

blocks of data are transferred.

 

 

Cause . . . . . :

RPG specifies MLTRCD(*YES) in

the UFCB

 

 

(User-File-Control Block). Records are passed between RPG

 

 

and data management in blocks. Positions 241 through the

 

 

end of the INFDS (File-Information-Data Structure) are

 

 

updated only when

a block of records is read or

written.

AS/400 specifications

The IBM AS/400, now known as the IBM iSeries, is a midrange computer system that has been a cornerstone of enterprise computing since its introduction in 1988. Designed to provide a robust platform for business applications, the AS/400 is celebrated for its reliability, scalability, and integrated database capabilities.

One of the key features of the AS/400 is its Integrated Operating Environment, which blends hardware and software resources seamlessly. This integration allows businesses to execute diverse workloads, ranging from traditional applications to modern web-based services, all on a single platform. The operating system, OS/400 (now IBM i), offers a rich set of APIs and tools for developers, simplifying application development and management.

Another standout characteristic of the AS/400 is its built-in database, DB2 for i. This powerful relational database management system allows for efficient data handling and provides advanced features such as support for SQL, XML, and JSON, making it easier for businesses to manage their data and integrate it with other systems. The database's tight integration with the operating system enables high performance and security.

In terms of scalability, the AS/400 can accommodate small businesses as well as large enterprises, with the ability to support hundreds of users simultaneously. Its architecture allows for easy upgrades in hardware, meaning that organizations can scale their systems without replacing the entire infrastructure.

Security is another critical attribute of the AS/400. With a sophisticated security model, it offers built-in user authentication, access control, encryption, and auditing capabilities to protect data and applications from unauthorized access.

The AS/400 also supports multiple programming languages, including RPG, COBOL, Java, and PHP, giving organizations the flexibility to choose the development tools that best fit their needs. This diversity helps maintain legacy applications while also developing new ones that leverage modern technologies.

Moreover, the platform supports both traditional green-screen interfaces and modern graphical user interfaces, allowing organizations to transition smoothly into contemporary user experience paradigms.

Overall, the IBM AS/400 stands out as a resilient, flexible, and secure computing platform that enables organizations to effectively manage their business operations, streamline processes, and adapt to changing market demands. Its unique combination of integrated features and capabilities ensures that it remains relevant in today's fast-paced technology landscape.
