Edit window with Breakpoint (red icon)
The Edit | Breakpoints menu option provides a useful debugging tool to create, test, and run a measurement routine. Generally, measurement routines are executed sequentially, line by line. By placing a breakpoint at a particular line in the measurement routine, the execution pauses when it reaches the breakpoint. If the measurement routine makes use of variable expressions and flow control, you can examine these variables to help ensure that the measurement routine functions as desired.
Once PC-DMIS pauses for the breakpoint, you can use
the Step Next button 
on the
Execution dialog box to continue the measurement
process one step at a time. This pauses the CMM after executing each step
of any command that tells the CMM to move. While in Step Mode, you can
insert additional hits into features, or you can insert new features between
existing features or commands. Step Mode can also be simulated offline.
When you are ready to continue with the measurement
routine's execution, click Continue 
on the Execution dialog box.
You can use menu and keyboard commands to speed up the placement and removal
of breakpoints. Breakpoints are saved with the measurement routine; they
remain available the next time you open the measurement routine.
If your measurement routine uses breakpoints and the Edit window is in Command mode, PC-DMIS continues to display the Edit window during execution but highlights the current command to execute in red. If the Edit window is in Summary mode, with a breakpoint, PC-DMIS shows:
Green highlight in the Edit window for already executed commands
Yellow for a feature about to be measured
Blue for features currently undergoing execution
Orange for non-executed commands.
