;; Description: ;AN000;
;; ------------ ;AN000;
;; This file contains the modules used to load the ;AN000;
;; GRAPHICS profile into resident memory. ;AN000;
;; ;AN000;
;; ************* The EGA Dynamic Save Area will be built (by ;AN000;
;; ** NOTE ** CHAIN_INTERRUPTS in file GRINST.ASM) over top of these ;AN000;
;; ************* modules to avoid having to relocate this save just before ;AN000;
;; terminating. This is safe since the maximum memory used is ;AN000;
;; 288 bytes and the profile loading modules are MUCH larger than ;AN000;
;; this. So GRLOAD.ASM MUST be linked before GRINST.ASM and after ;AN000;
;; GRPRINT.ASM. ;AN000;
