IBM AS/400 manual Removing All Job and, Debug Commands, Setting and Removing Watch Conditions

Setting and Removing Watch Conditions

To remove a conditional thread breakpoint using the Work with Module Bre display:

1. Type 4 (Clear) Optin fitheld next to the breakpoint you want to remove

2. Press Enter.

Using	the	TBREAK or CLEAR		Debug Commands
You	use	the	same syntax for the TBREAK debug command			as	you	would	fo
BREAK	debug command. The difference between these				commands		is	that	th
BREAK	debug command sets a conditional job breakpoint				at	the same posit
all	threads,		while the TBREAK debug command sets a		conditional			thread	b
point in		the	current thread.
To remove		a	conditional	thread breakpoint, use the	CLEAR	debug		command.
When	a conditional thread breakpoint is removed, it				is	removed		for	the
thread only.

Removing All Job and	Thread	Breakpoints
You	can	remove	all job and	thread		breakpoints,		conditional		and unconditio
a program object that has				a	module	object	shown on		the	Display	Module
display by using the CLEAR				PGM	debug	command.	To	use	the	debug	command,
type:
CLEAR PGM
on the debug command line.				The	breakpoints are			removed from all			of the
bound to		the	program.

Setting and Removing	Watch	Conditions
You	use watch condition		to monitor	if	the current value of an expression
variable		changes	while your program runs. Setting watch conditions is sim
setting		conditional	breakpoints,	with	one important difference:

¹Watch conditions stop the program as soon as the value of a watche

expression or variable changes from its current value.

¹ Conditional job breakpoints	stop the program only if a variable change
value specified in the	condition.

The debugger watches an expression or a variable through the contents storage address , computed at the time the watch condition is set. When content at the storage address is changed from the value it had whe condition was set or when the last watch condition occurred, the progr

Note: After a watch condition has been registered, the new contents a watched storage location are saved as the new current value of sponding expression or variable. The next watch condition will be if the new contents at the watched storage location change subs
