The RPG IV source specification layouts differ significantly

from

RPG

and

the

OPM RPG/400

layouts.

For

example,

the

posi

entries

on

the specifications have changed and

the

types

of

specif

have also changed. The RPG IV specification layouts are not compati

previous layouts. To take advantage

of

RPG

features,

you

must

source

members

in

your

applications

to the

RPG

source

Note:

The valid types of source members you

can

convert

are

RPG,

RPT

RPG38, RPT38, SQLRPG, and blank. The Conversion Aid does not support

conversion

of

types.

on page 382 and follow the general directions.

Conversion Overview

You

convert

source

programs

to

the

RPG

IV

source

format

by

calling

sion

Aid through the CL command Convert RPG

Source

(CVTRPGSRC).

The

Con-

version

Aid

converts:

¹

A

single

member

¹

All

members in a source physical file

¹

All

members

with

a common member-name prefix

in

the same

file

To

minimize

the likelihood of there being

conversion

problems,

you

can

have

the

/COPY

members

included

in

the

converted

source

code. For

co

in reading the code, you can also optionally include specification te

converted

source

code.

The Conversion Aid converts each source member on a line-by-line basis. each member conversion, it updates a log file on the status of the specified a log file on the command. You can also obtain a conversi includes information such as conversion errors, /COPY statements, CALL ope ations, and conversion status.

To see Conversion Aid can identify, you can run the Conversion Aid using the member as input, and specify a conversion report but no output membe mation on the types of coding that cannot be converted, see “Resolvi Problems” on page 398.
