Command
This chapter shows you how to create an ILE program using RPG IV source with
the Create Bound RPG Program (CRTBNDRPG) command. With this command
you can create one of two types of ILE programs:
the Create Bound RPG Program (CRTBNDRPG) command. With this command
you can create one of two types of ILE programs:
1. OPM-compatible programs with no static binding
2. Single-module ILE programs with static binding
Whether you obtain a program of the first type or the second type depends on
whether the DFTACTGRP parameter of CRTBNDRPG is set to *YES or *NO
respectively.
whether the DFTACTGRP parameter of CRTBNDRPG is set to *YES or *NO
respectively.
Creating a program of the first type produces a program that behaves like an OPM
program in the areas of open scoping, override scoping, and RCLRSC. This high
degree of compatibility is due in part to its running in the same activation group as
OPM programs, namely, in the default activation group.

degree of compatibility is due in part to its running in the same activation group as
OPM programs, namely, in the default activation group.
However, with this high compatibility comes the inability to have static binding.
Static binding refers to the ability to call procedures (in other modules or service
programs) and to use procedure pointers. The inability to have static binding means
that you cannot:
Static binding refers to the ability to call procedures (in other modules or service
programs) and to use procedure pointers. The inability to have static binding means
that you cannot:
¹
Use the CALLB operation in your source
¹
Call a prototyped procedure
¹
Bind to other modules during program creation
Creating a program of the second type produces a program with ILE characteristics
such as static binding. You can specify at program-creation time the activation
group the program is to run in, and any modules for static binding. In addition, you
can call procedures from your source.

Using the CRTBNDRPG Command
The Create Bound RPG (CRTBNDRPG) command creates a program object from
RPG IV source in one step. It also allows you to bind in other modules or service
programs using a binding directory.
RPG IV source in one step. It also allows you to bind in other modules or service
programs using a binding directory.
The command starts the ILE RPG compiler and creates a temporary module object
in the library QTEMP. It then binds it into a program object of type *PGM. Once the
program object is created, the temporary module used to create the program is
deleted.

program object is created, the temporary module used to create the program is
deleted.
The CRTBNDRPG command is useful when you want to create a program object
from standalone source code (code that does not require modules to be bound
together), because it combines the steps of creating and binding. Furthermore, it
allows you to create an OPM-compatible program.

Note: If you want to keep the module object in order to bind it with other modules
into a program object, you must create the module using the CRTRPGMOD
