; This is file: LOGO.PCH

;The following command should be applied to LOGO
;to patch it to work with FANSI-CONSOLE.
;Note that this is unnecessary if you have an EGA.
;This is for the IBM LOGO version 1.00 ONLY!
;After the patch is made, LOGO will not work
;without FANSI-CONSOLE.
;The commented lines (ones starting with semi-
;colons) may generate error text but that is OK.
;Note that the patched routine may not be in exactly
;the same place in your version of LOGO.
