# Setting and Removing Breakpoints

Breakpoints are set by clicking in the breakpoint area, which is the narrow grey area where the line numbers for the source file are displayed. When you hover the mouse to the left of the line numbers, the cursor changes to a hand icon to show that clicking in that spot sets a breakpoint.

1. To set a breakpoint, click in the breakpoint area to the left of the line where you want to set the breakpoint.
   A red disk appears to show that a breakpoint was set.
2. To remove a breakpoint, click on the red disc icon in the breakpoint area to the left of the line where you want to remove the breakpoint.
   The red disc icon disappears from the breakpoint area.
3. To disable a breakpoint, open the Debugger sidebar if it is not already open, by clicking on its name and in the breakpoints section, clear the checkbox for the breakpoint that you want to disable.
   The debugger no longer suspends at this breakpoint, until you enable it again.
4. To disable all breakpoints in the model, open the Debugger sidebar if it is not already open, by clicking on its name and click the Toggle Breakpoints button, which is the fifth button from the left in the Debugger sidebar.
   Note: Conditional breakpoints are not supported in this version of Xpress Workbench.
   Note: Breaking automatically on exceptions is not supported in this version of Xpress Workbench.
