Abstract: A method for use in indicating an execution of application source code. Application object code is generated based on application source code. The application object code includes a plurality of object code portions of interest corresponding to a plurality of source code portions of interest within the application source code. An execution breakpoint is associated with each object code portion of interest. When an object code portion of interest is executed, the corresponding execution breakpoint is removed, and an execution event is associated with the corresponding source code portion of interest. Source code portions of interest that are associated with an execution event may be indicated by a presentation interface.
