(SEU)

 

 

 

 

 

 

 

You

can

use

the

Source Entry

Utility (SEU)

to enter your source stat

also provides prompting for the different specification templates as we

checking.

To start

SEU, use the STRSEU (Start

Entry

Utility)

comma

If

you

name

your

source

file

QRPGLESRC,

SEU

automatically

sets the

sour

to RPGLE

when it starts the editing session

for a new member. Otherwis

have

to

specify

RPGLE when

you create

the

member.

 

 

 

If you need prompting after you type STRSEU, press F4. The STRSEU dis appears, lists the parameters, and supplies the default values. If y eter values before you request prompting, the display appears with t filled in.

In the following example you enter source statements for a program whi employee information from a master file. This example shows you how to:

¹Create a library

¹ Create a source physical file

¹ Start an SEU editing session

¹Enter source statements.

1. To create a library called MYLIB, type:

CRTLIB LIB(MYLIB)

The CRTLIB command creates a library called MYLIB.

2. To create a source physical file called QRPGLESRC type:

CRTSRCPF FILE(MYLIB/QRPGLESRC) RCDLEN(112)

TEXT('Source physical file for ILE RPG programs')

The CRTSRCPF command creates a source physical file QRPGLESRC in library MYLIB.

3. To start an editing session and create source member EMPRPT type:

STRSEU SRCFILE(MYLIB/QRPGLESRC)

SRCMBR(EMPRPT)

TYPE(RPGLE) OPTION(2)

Entering OPTION(2) indicates that you

want

to

start

a

session

for

a

member. The STRSEU command creates a

new

member EMPRPT

in

file

 

 

QRPGLESRC in

library MYLIB and

starts

an

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.
