Tracer
Setting watch variables

Set a watch variable to detect that processing has changed the value of a property.

After you set a watch variable, you can minimize the Tracer window and use the system. Focus returns to the Tracer window when your work causes the property value to change.

1. Click Watch and complete the Watch Variables form.

   Field	Completing the field
   Page Name	Enter the name of the page, or enter param for the parameter page.
   Property Name	Enter the property name. Don't type a period before the name of the property.
   Or Page Messages	Select to watch this page for page messages.

2. Click Set Watch to save the entered information.
3. Minimize the Watch Variables form and the Tracer window.
4. Resume other work.
5. When the Tracer next detects a change in the property value, it displays a Property Inspector area in the lower left area of the event window.
6. To see the full Property Inspector window, place your pointer at the line until a yellow arrow appears. Drag up until the complete Property Inspector window is visible.

   The Property Inspector window displays:

   Field	Description
   Reference	The page and property being watched.
   Old Value	If you clicked Continue, and the Tracer tool finds that the value has changed, it lists the previous value here.
   Current Value	The current value of the property.

7. Click Continue to resume tracing. If you don't resume processing within an hour after a break, processing resumes automatically.

To end the watch, access the Watch Variables form again, select the Remove check box, and click Remove .
