IBM AS/400 manual Setting and Removing Breakpoints, Unconditional

Setting and Removing Breakpoints

is	shown	with the source positioned at the line where the breakpoint
line	is	highlighted. At	this point, you can evaluate fields, set more
run	any	of the debug	commands.

You should know the following characteristics about breakpoints before

¹When a breakpoint is set on a statement, the beforebreakpointthat occurs statement is processed.

¹When a statement with a conditional breakpoint is reached, the cond expression associated with the breakpointbeforeis theevaluatedstatement is

processed. If the expression is true, the breakpoint takes effec program stops on that line.

¹ If	the line	on which	you	want	to	set	a breakpoint is not a runnab
the	breakpoint	will be	set	on	the	next	runnable statement.

¹ If a breakpoint is bypassed that breakpoint is not processed.

¹Breakpoint functions are specified through debug commands. These fun include:

– Adding breakpoints to program objects

– Removing breakpoints from program objects

– Displaying breakpoint information

–Resuming the running of a program object after a breakpoint has reached

– You can either have

a

job or thread breakpoint on a specified

the

same

time,

but

not

both.

If

you

change

the

view

of

the

module

after

setting breakpoints,

the

numbers

of

the

breakpoints

are mapped to

the

new view by the source

If

you

are

debugging

a

module

or program

created with a statement

can

set

or

remove breakpoints

using statement numbers obtained from

the

listing.

Setting and Removing	Unconditional	Job	Breakpoints
You	can set	or	remove an unconditional Job breakpoint by using:

¹F6 (Add/Clear breakpoint) or F13 (Work with module breakpoints) from th

Display Module Source display

¹	The	BREAK	debug	command to set a job breakpoint
¹	The	CLEAR	debug	command to remove a jobbreakpoint

¹The Work with Module Breakpoints display.

The simplest way to set and remove an	unconditional job breakpoint is t
(Add/Clear breakpoint). The function key	acts	as	a	toggle and	so	it wi
breakpoint from the line your cursor is	on,	if	a	breakpoint	is	alread

To remove an unconditional job breakpoint using F13 (Work with module bre points), press F13 (Work with module breakpoints) from the Display Module
