 ;
SHARE(RGZSTR) ; determine if the patient is shared:
 ; a) If shared, return one to RGADT1 and call GENERATE^HLMA
 ; b) If not shared and the host facility is the CMOR, update
 ;    host TFL record, do not call GENERATE^HLMA
 ; c) If not shared and the host facility is not the CMOR, add
 ;    the CMOR to the subscription list, return one to RGADT1

 ; note: 1) Event Type will equal A01 or A03.  This needs to be
