A breakpoint can be modified to make it print an expression and its value when it is reached.
Again suppose that you have reached a breakpoint on the call to
+
as set in the example above. To make this breakpoint print, choose
Printing...
from the Breakpoint Options menu: Enter a valid Lisp expression in the Printing tab of the Breakpoint Options dialog, and click OK.
When the breakpoint is reached, the expression and its value are printed like this:
Stepper value (+ 4 4 4 4): 16
If you check the Print without stopping option, then the above line is printed but the code continues to execute and does not stop at the breakpoint.
Note: you cannot currently access the values of local variables in the printed expression.
