 The DEBUG command forces a task to trap to a debugging aid by setting
 the T-bit in the task's Processor Status Word (PSW).  To debug a task,
 it must have been built with the /DA switch or have issued a SPECIFY
 SST VECTOR TABLE FOR DEBUGGING AID (SVDB$) directive.

 Nonprivileged users can debug any nonprivileged task that was initiated
 from their own terminals (TI:).  Privileged users can debug any task.

 The format of the DEBUG command is:

	DEB[UG] [taskname]

 where taskname is the name of the task to be debugged.  If taskname is
 not specified, DEBUG looks for the task currently running from the
 issuing terminal (task TTnn).
