Preparing a Program for

Debugging

A program or module must have debug

data

available

if

you

are

to

de

debug

data

is

created during compilation, you specify whether a modu

contain

debug

data

when you create

it

using CRTBNDRPG or CRTRPGMOD. You

use the DBGVIEW parameter on either

of

these

commands

to

indicate

w

data

(if

any)

is to

be

created

during

compilation.

The

type

of

debug

data

that

can

be

associated

with

a

module

is

r

debug

view

.

You

can

create

one

of

the

following

views for

each

module

want

to

debug.

They

are:

¹

Root

source

view

¹ COPY source view

¹Listing view

¹Statement view

The default value for both CRTBNDRPG and CRTRPGMOD is to create a stat ment view. This view provides the closest level of debug support to p releases.

If you do not want debug data to be included with the module or i compilation time, specify DBGVIEW(*NONE) when the module is created. However, a formatted dump will not list the values of program variables debug data is available.

Note also that the storage				requirements for a	module	or program	will va
what	depending	on the	type	of debug data included with it. The foll
the	DBGVIEW parameter		are	listed in increasing	order	based on	their
ondary storage		requirements:

1.*NONE

2.*STMT

3.*SOURCE

4.*COPY

5.*LIST

6.*ALL

Once you have created a module with							debug	data	and	bound	it into a
object (*PGM), you		can start		to	debug		your program.
Note: An OPM program must be compiled with OPTION(*SRCDBG) or
OPTION(*LSTDBG)		in	order	to	debug it using			the	ILE	source	debugge
more	information,		see “Starting			the	ILE Source Debugger” on page 1
The debug	views	are	summarized		in	the	following table:
