158 Working with Diagrams
Inserting a Breakpoint
Use the Breakpoint option on the Diagram menu to set or clear
breakpoints. You can set and clear breakpoints using the Diagram menu
or Online Toolbar but you must be online to set a breakpoint.
Breakpoints can only be set after the diagram is downloaded. The
diagram must be downloaded every time a change is made to the diagram.
Select Download Diagram from the Diagram menu option. To display
the Breakpoint Control dialog box, select the block where you want to set
a breakpoint.
Select Insert/Remove Breakpoint. A black validation check mark
appears next to the block with a breakpoint that is set.
Note: Select Clear All Breakpoints to clear breakpoints.
For more information about the breakpoint option, see the Going Online
chapter.
