 Q MEDIAN
 ; The median value in an array of an odd number of items is
 ; the value of the middle item.  (If there are 5 items, the 3rd is
 ; the median.)
 ; The median value in an array of an even number of items is the
 ; average of the two middle items.  (If there are 6 items, the median
 ; is the average of the 3rd and 4th items.)
 ; Example:
 ;                  values   number of items per value
 ;                       |   |
 ; S GBTEST(1,"CT","IP",30)=3
 ; S GBTEST(1,"CT","IP",148)=1
 ; S GBTEST(1,"CT","IP",160)=1
 ; S GBTEST(1,"CT","IP",365)=1
 ; So we've got 3 items with a value of 30, and 1 item each at 148,
 ; 160, and 365.
 ; S TOTITEMS=6   (That's 3+1+1+1)
 ; Now invoke the function.  The first arg is the total number of items.
 ; The second arg is the 'root' of the array up to, but not including
 ; the values.  The root must be in quotes.
 ; S MEDVAL=$$MEDIAN(TOTITEMS,"GBTEST(1,""CT"",""IP"",")
 ; (MEDVAL should be 89)
