Sure. Use whatever tools help. My problem with flowcharts is ensuring that the chart represents the actual code. I have made the mistake of 'seeing what should be there instead of what is there' more times than I care to admit.
I often use breakpoints to trace the execution path. Set breaks on every line and run it with various books. This technique can also help determine why when you have a book that produces the wrong value.
