Setting breakpoints in C++ using AT CALL

AT CALL gives z/OS® Debugger control when the application code attempts to call the specified entry point. The entry name must be a fully qualified name. That is, the name shown in DESCRIBE CU must be used. Using the example
AT ENTRY shapes::square(int)
to set a breakpoint on the method square, you must enter:
AT CALL shapes::square(int)
even if square is uniquely identified.
