 ; DFN       Patient's internal entry number in the Patient file
 ; FDATE     "From" date
 ; TDATE     "Thru" date, default=today
 ; HI        1=keep track of individual patient usage
 ;           0=don't keep track
 ; Data will be rolled up into the following global:
 ; ^TMP("SPN",$J,"OP",
 ; with the following nodes:
 ; "PAT")                # patients
 ; "VISITS")             # visits
 ; "VISITS",-visits)     # patients who made this many visits
 ; "STOPS")              # stops
 ; "SC",stopcd)          # patients who stopped at this stop code
 ; "SC",stopcd,"NAME")   name of the stop code
 ; "SC",stopcd,"VISITS") # visits to this stop code
 ; "SC",stopcd,"STOPS")  # stops to this stop code
 ; ... and individual patient usage ...
 ; "HI","H1",-visits,-ndscnums,DFN)
 ; NOTE:  A visit is when a patient goes to a hospital on a given day.
 ;        A stop is when a patient goes to a stop code (clinic) in the
 ;        hospital.  There can be any number of stops per visit.
 ;        Now for the tricky part....
 ;        Visits to a stop code are calculated by dividing the visit (1)
 ;        by the number of >different< stop codes gone to.  So if four
 ;        different clinics were gone to, then each gets .25 visit.
 ; The following global is used as a scratch pad:
 ; ^TMP("SPN",$J,"TMP":
 ; "SC",scnum,date)="" this stop code was visited on these dates
 ; "VI",date,scnum)="" these stop codes were visited on this date
 ; "VI",date)          # different stop codes visited on this date
