CRTBNDRPG Command

*YES

When this program is called it will always run in the default ac group. The default activation group is the activation group where program model (OPM) programs are run.

Specifying

DFTACTGRP(*YES) allows ILE RPG programs to

behave like

OPM programs

in the areas of override scoping,

open scoping, and

RCLRSC.

 

 

ILE static binding is not available when a program is created wi DFTACTGRP(*YES). This means that you cannot use the BNDDIR or

ACTGRP parameters when creating this program. In addition, any call operation in your source must call a program and not a procedure

DFTACTGRP(*YES) is useful when attempting to move an application on a program-by-program basis to ILE RPG.

*NO

The program is associated with the activation group specified b

ACTGRP parameter. Static binding is allowed when *NO is specified.

If ACTGRP(*CALLER) is specified and this program is called by a p running in the default activation group, then this program will beh according to ILE semantics in the areas of file sharing, file s

RCLRSC.

DFTACTGRP(*NO) is useful when you intend to take advantage of ILE concepts; for example, running in a named activation group or bindi service program.

OPTION

Specifies the options to use when the source member is compiled. Y specify any or all of the options in any order. Separate the opti more blank spaces. If an option is specified more than once, the used.

*XREF

Produces a cross-reference listing (when appropriate) for the sou member.

*NOXREF

A cross-reference listing is not produced.

*GEN

Create a program object if the highest severity level returned piler does not exceed the severity specified in the GENLVL opt

*NOGEN

Do not create a program object.

*NOSECLVL

Do not print second-level message text on the line following the f message text.

*SECLVL

Print second-level message text on the line following the first-level text in the Message Summary section.

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.
