数组中最大最小值判断的指令是什么？

比如数组：data[120]=
{12.45,12.33,12.34,12.36,12.37,12.32,12.33,12.38,12.35,12.34,12.31,12.29,12.35,12.33,12.34,12.36,12.37,12.32,12.33,12.38,12.35,12.3
4,12.31,12.29,12.35,12.33,12.34,12.36,12.37,12.32,12.33,12.38,12.35,12.34,12.31,12.29,12.35,12.33,12.34,12.36,12.37,12.32,12.33,12.
38,12.35,12.34,12.31,12.29,12.35,12.33,12.34,12.36,12.37,12.32,12.33,12.38,12.35,12.34,12.31,12.29,12.35,12.33,12.34,12.36,12.37,12
.32,12.33,12.38,12.35,12.34,12.31,12.29,12.35,12.33,12.34,12.36,12.37,12.32,12.33,12.38,12.35,12.34,12.31,12.29,12.35,12.33,12.34,1
2.36,12.37,12.32,12.33,12.38,12.35,12.34,12.31,12.29,12.35,12.33,12.34,12.36,12.37,12.32,12.33,12.38,12.35,12.34,12.31,12.29,12.35,
12.33,12.34,12.36,12.37,12.32,12.33,12.38,12.35,12.34,12.31,12.21},  要找出其中最大、最小值，该用何命令？
另外，我想把这120个数据分别在120个数据显示元件中显示，有什么简便指令？
谢谢！！

for x=0 to 119
  for y=0 to 119
    if data[x]<data[y] then
      b=data[x]
      data[x]=data[y]
      data[y]=b
    end if
  next y
next x

最后的data[0]就是最小值。

发送到寄存器 用Setdata函数。
