• Select a variable in the Data component, and left mouse button + W key to set a
Write watchpoint on the selected variable. A red vertical bar is displayed on the left
side of the variables on which a write watchpoint has been defined. If write access is

Write watchpoint on the selected variable. A yellow vertical bar is displayed for the
variables on which a read/write watchpoint has been defined. If the variable is

displayed in all window components.
• Select a variable on which a watchpoint was previously defined in the Data
component, and left mouse button + D key to delete the watchpoint on the selected
variable. The vertical bar previously displayed for the variables is removed.
• Select a variable in the Data component, and left mouse button + S key to set a
watchpoint on the selected variable. The Watchpoints Setting dialog box opens. A

Expression Editor
To add your own expression (in EBNF notation) double-click a blank line in the Data
component window to open the Edit Expression dialog box shown in
Figure 3.19 , or
