;	 Error Codes
;	=============
;
;    The following errors are those which a disk error  routine  may  normally
; expect  to  be  passed,  although such a routine should be general enough to
; handle any error code.
;
	const	.NCOMP, 0FFh	;Incompatible disk
	const	.WRERR, 0FEh	;Write error

;
;
;    The following are errors which the KBDOS may pass to the  ABORT  routine.
; Of  cource  a  user  abort routine may see any other error but these are the
; ones which are generated internally and may require special case handling.

				;090h /
;
;
;    The following errors are those generated by COMMAND2.COM.  These will not
; be  returned from KBDOS functions, but user application programs may find it
; useful to return some of these errors.
;

	const	.PRAK,  07Eh	;Press any key to continue...
;
				;07Dh \
				; ..   > Reserved for future use
				;040h /
;
;
;    Error codes below 40h may be used by user programs for any purpose  which
; they desire, and will be guarenteed to be different from any errors returned
; by the system.  COMMAND2.COM will not print an error message  for  codes  in
; the range 00h...1Fh.
