Using the CRTBNDRPG Command

Chapter 6. Creating	a	Program		with		the		CRTBNDRPG
Command
This	chapter		shows		you		how	to create an ILE program using RPG IV s
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 typ whether the DFTACTGRP parameter of CRTBNDRPG is set to *YES or *NO respectively.

Creating	a	program	of	the	first type	produces a program that behav
program	in the areas			of open scoping,		override scoping, and RCLRSC. Thi
degree	of	compatibility is			due in part to its running in the same
OPM programs,		namely,	in	the	default activation group.

However, with this high compatibility comes the inability to have sta Static binding refers to the ability to call procedures (in other m programs) and to use procedure pointers. The inability to have stati that you cannot:

¹ Use the CALLB operation in your source

¹ Call a prototyped procedure

¹Bind to other modules during program creation

Creating		a program of the second				type produces a program	with	ILE
such	as	static binding.		You	can	specify at program-creation	time	the
group the program is			to	run	in,	and any modules for static	binding.
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

mo

programs

using a

binding

directory.

The

command

starts

the

ILE RPG

compiler

and creates a temporary modu

in

the

library

QTEMP. It

then

binds it

into

a program object

of

typ

program object is created, the temporary module used to create th deleted.

The CRTBNDRPG command is useful when you want to create a program obj from standalone source code (code that does not require modules to

together),

because

it

combines the steps of

creating and

binding.

F

allows

you

to create an OPM-compatible

program.

Note:

If

you

want

to

keep

the

module

object

in

order

to

bind it

into

a

program

object,

you

must

the
