;   This file contains all global data that must be modified at interrupt

;   named INTDATA.  Only things that must be accessed and modified at
;   interrupt level may be placed in this file.  All values here must be
;   referenced as FAR in the code.
;
;   The creation of this segment allowed USER to eliminate all code segment
;   variables.  This was needed for protect mode as well as moving USER's
;   text segment into HIMEM.
