BREAK <Xenix error codes>
;
; XENIX calls all return error codes through AX. If an error occurred then
; the carry bit will be set and the error code is in AX. If no error occurred
; then the carry bit is reset and AX contains returned info.
;
; Since the set of error codes is being extended as we extend the operating
; system, we have provided a means for applications to ask the system for a
; recommended course of action when they receive an error.
;
; The GetExtendedError system call returns a universal error, an error
; location and a recommended course of action. The universal error code is
; a symptom of the error REGARDLESS of the context in which GetExtendedError
; is issued.
