Action Points
The following action point commands define and manipulate the points at which the flow of program execution should stop so that you can examine debugger or program state:
dactions: Views information on action point definitions and their current status; this command also saves and restores action points.
dbarrier: Defines a process barrier breakpoint.
ddisable: Temporarily disables an action point.
denable: Re-enables an action point that has been disabled.
