Creating a Root Source View

A root source view contains text from the root source member. This view contain any /COPY members. Furthermore, it is not available if the roo member is a DDM file.

You

create a

root

source

view

to

debug a module

by using

the

*SO

or

*ALL

options

on the DBGVIEW parameter for

either

the

CRTRPGMOD or

CRTBNDRPG commands

when

you create

the

module.

 

 

 

 

 

 

The compiler creates the root source

view

while

the

module object

being

compiled.

The

root

source

view is created using references

t

text in the root source member

rather

than

copying

 

the

text

of

th

module

object.

For this reason, you should not modify, rename, or

mov

source

members

between

the

module

creation

of these

members

and

th

ging of the module created from

these

members.

If

 

you

do,

the

vi

source

members

may

not be

usable.

 

 

 

 

 

 

 

 

 

 

For example, to create a root source view for a program DEBUGEX wh CRTBNDRPG, type:

CRTBNDRPG PGM(MYLIB/DEBUGEX) SRCFILE(MYLIB/QRPGLESRC)

TEXT('ILE RPG/400 program DEBUGEX')

DBGVIEW(*SOURCE)

To create a root source view for a module DBGEX when using CRTRPGMOD type:

CRTRPGMOD MODULE(MYLIB/DBGEX) SRCFILE(MYLIB/QRPGLESRC)

TEXT('Entry module for program DEBUGEX')

DBGVIEW(*SOURCE)

Specifying DBGVIEW(*SOURCE) with either create command creates a root view for debugging module DBGEX. By default, a compiler listing with members and expanded DDS, as well as other additional information is

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.
