Setting and Removing Breakpoints

5.After the breakpoint is set, press F12 (Cancel) to leave the Wor Breakpoints display. Press F3 (End Program) to leave the ILE source debugger. Your breakpoint is not removed.

6.Call the program. When a breakpoint is reached, the program stops Display Module Source display is shown again. At this point you ca through the program or resume processing.

Example

of Setting a Conditional Job Breakpoint Using the

BREAK

Command

In this example, we want to stop the program when the date field certain value. To specify the conditional job breakpoint using the BR

1. From the Display Module Source display, enter:

break 128 when BigDate='1994-09-30'

A conditional job breakpoint is set on line 128.

2.After the breakpoint is set, press F3 (End Program) to leave the debugger. Your breakpoint is not removed.

3.Call the program. When a breakpoint is reached, the program stops Display Module Source display is shown again.

National Language Sort Sequence (NLSS)

Non-numeric conditional breakpoint expressions are divided into the follo types:

¹Char- 8: each character contains 8 bits

This corresponds to the RPG data types of character, date, time timestamp.

¹Char-16: each character contains 16 bits (DBCS)

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.
