ILE Application Using CRTRPGMOD

¹An advanced application

The effect of ILE is the same as described in “Effect of ILE” on

You may want to read about the basicILEILEConconceptsbeforein using this approach.

Method

Because

this

approach

is

the most flexible, it includes a number

of

you

might

create

an

ILE

application.

The

following

list

describes the

you

may

need

to

perform:

1. Create

a

module

from

each

source

member using

the

appropriate

com

for

example, CRTRPGMOD

for RPG

source,

CRTCLMOD for CL

source, etc..

2. Determine the ILE characteristics for the application, for example:

¹

Determine

which

module

will

contain

the

procedure

that will

be

th

point

for

the

application.

The

module

you

choose

as

the

entry

m

first

one

that

you want

to get control.

In

an

OPM

application,

th

the

command

processing

program,

or

the

program called

because

a

item

was

selected.

¹

Determine

the

activation

group

the application will run in. (Most l

will want to

run

in

a

named

activation

group,

where

the name

is

the

name

of

the

application.)

¹

Determine

the

exports

and

imports

to

be

used.

3. Determine if any of the modules

will be bound together to create

program.

If

so,

create

the

service

programs

using

CRTSRVPGM.

4. Identify

the

names

of

the binding directories, if any, to be us

It

is

assumed

with

this

approach that if you are using a binding

one

that

is

already created for you. For example, there may be

service

program

that

you

may

want

to

bind

to

your

source. Consequen

you need

to

know

is

the

name

of

the binding

directory.

5.Bind the appropriate modules and service programs together using CRTP specifying values for the parameters based on the characteristics step 2.

An	application	created using this approach can run fully protected,					tha
own	activation	group.	Furthermore, it	can be	updated easily	through	us
UPDPGM or UPDSRVPGM commands. With these commands you can add						or
replace one		or more	modules without	having to	re-create the	program	ob

Single-Language ILE Application		Scenario
In	this	scenario		you	compile		multiple	source files	into modules	and bind
one	program		that	is called		by	an ILE	RPG program.	Figure 8 on	page 29
the	run-time		view	of	this	application.
