;The following command should be applied to DOSEDIT
;to patch it to work with FANSI-CONSOLE, or any
;machine emulating the IBM PC ROM BIOS video calls.
;Note that this is unnecessary if you use
;the FANSI-CONSOLE /Y=1 option.
;This is for the DOSEDIT version dated 05-09-84.
;(Use DEBUG to display at 100).
;After the patch is made, DOSEDIT will still
;also work without FANSI-CONSOLE.
;The commented lines (ones starting with semi-
;colons) will generate error text but that is OK.
