   7 ; the carry bit will be set and the error code is in AX.  If no error occurred
   8 ; then the carry bit is reset and AX contains returned info.
   9 ;
  10 ; Since the set of error codes is being extended as we extend the operating
  11 ; system, we have provided a means for applications to ask the system for a
  12 ; recommended course of action when they receive an error.
  13 ;
  14 ; The GetExtendedError system call returns a universal error, an error
  15 ; location and a recommended course of action.  The universal error code is
  16 ; a symptom of the error REGARDLESS of the context in which GetExtendedError
  17 ; is issued.
