A
; This is file: IBMMODE.310
;
; This is a patch file for the IBM-DOS 3.10 MODE command.
;
; DO NOT USE THIS FILE WITH *ANY* OTHER VERSION OF DOS!
;
; To use this file:
; DEBUG MODE.COM <IBMMODE.310
;
; These patches are for programming errors in IBM-DOS 3.10.
; Since it is not our job to make all versions of DOS correct,
; it is up to you yourself or the manufacturer of your version
; of DOS to make similar fixes if your DOS has similar problems.
; We will provide similar patches only for other MS-DOS versions ONLY
; if they come STRAIGHT from Microsoft with ***NO*** modifications!
; IF you have ENOUGH programming background, you may use the comments
; for each patch to find similar code in your NON-IBM NON-Microsoft
; or NON-3.10 version of DOS and make appropriate patches ON YOUR OWN.
