Note the following about the converted source:

¹The new specification types are H (control), F (file), D (definitio

(calculation), and O (output); they must be entered in this order.

The converted source contains specification templates for the new ty INSRTPL(*YES) was specified on CVTRPGSRC.

¹ The	control,	file,	and definition specifications are keyword-oriented.
4	- 7, and	9 -	16.

¹The ILE member has a new specification type, definition. It is us

standalone fields, arrays and named constants as well as data struct

In this example,
–	ARR2	is	defined	as	a	standalone	array (Line 9)
–	Data	structure DS1 is				defined as	a data structure with two su
	and	ARR1	(Lines	11	-	14)

– Constant CONST1 is defined as a constant (Line 16)

The input (I) specifications are now used only to define records file. See Lines 19 - 20.

¹ The	extension	(E)	specifications have been eliminated. Arrays and ta
now	defined	using	definition specifications.

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.
