Strategy 2: ILE Program	Using	CRTBNDRPG
Strategy 2 results in an				ILE program		that	can take advantage of ILE
Your source can contain static procedure							calls because you can bind
other	modules	or	service	programs	using a		binding directory. You can
the activation group in which the					program		will	run.
Method
Use	the following		general	approach	to	create		such a program:

1.If starting with RPG III source, convert your source to RPG I CVTRPGSRC command.

If converting, be sure to convert all /COPY members and any progra called by the source you are converting. Also, if you are using program, you should also make sure that you are using ILE CL inste CL.

2. Determine the activation group the program will run in.

You may want to name it after the application name, as in this e

directory.

4. Create an ILE program using CRTBNDRPG, specifying DFTACTGRP(*NO), the activation group on the ACTGRP parameter, and the binding directory, on the BNDDIR parameter.

Note that if ACTGRP(*CALLER) is specified and this program is called by program running in the default activation group, then this program will according to ILE semantics in the areas of override scoping, open s

RCLRSC.

The main drawback of this strategy is that you do not have a perm object that you can later reuse to bind with other modules to cre program. Furthermore, any procedure calls must be to modules or servi grams that are identified in a binding directory. If you want to modules without using a binding directory when you create the progra to use the third strategy.
