Converting Your Source

Converting All Members in a File

You can convert all of the members in a source physical file by spe FROMMBR(*ALL) and TOMBR(*FROMMBR) on the CVTRPGSRC command. The

Conversion Aid will attempt to convert all members in the file specified. member should fail to convert, the conversion process will still continue.

For

example, if you want to

convert all source members in the file QRP

the

file QRPGLESRC, you would

enter:

CVTRPGSRC FROMFILE(OLDRPG/QRPGSRC)

FROMMBR(*ALL)

TOFILE(NEWRPG/QRPGLESRC)

TOMBR(*FROMMBR)

This command converts all of the source members in library OLDRPG in the physical file QRPGSRC. The new members are created in library NEWRPG in source physical file QRPGLESRC.

If

you prefer to

keep all source

(DDS source, RPG source, etc.) in

you can still convert the RPG source

members in one step, by specifyi

FROMMBR(*ALL). The Conversion Aid

will only

convert members with a valid RPG

type

(see Table 30

on page

380).

If

you

need

to convert only some members that

are

in

a source

physi

these members

share

a

common prefix in

the

member

name,

then you

can

them

by

specifying

the

prefix followed

by

an

* (asterisk).

 

For example, if you want to convert all members with a prefix of PAY, enter:

CVTRPGSRC FROMFILE(OLDRPG/QRPGSRC)

FROMMBR(PAY*)

TOFILE(NEWRPG/QRPGLESRC)

TOMBR(*FROMMBR)

This command converts all of the source members in library OLDRPG in the physical file QRPGSRC. The new members are created in library NEWRPG in source physical file QRPGLESRC.

Performing a Trial Conversion

You can

do

a

trial run

for

any

source member that you suspect you

lems converting. You will then

get

a conversion report for the converted

member

that

may

identify

certain

conversion errors.

For example, to perform a trial conversion on the source member PAYROLL,

CVTRPGSRC FROMFILE(OLDRPG/QRPGSRC)

FROMMBR(PAYROLL)

TOFILE(*NONE)

The

TOMBR parameter should be specified as *FROMMBR. However, since

thi

the

default, you do not need to specify it unless the default

value

changed. The CVTRPT parameter should be specified as *YES — this is a default. If it is not, then the conversion will stop immediately.

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.
