25.6.3 Printing breakpoints

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.
