VFP编写程序，任意数排列。

1.编写程序，由键盘输入5个任意数，请把此5个数由大到小进行排序。
2.计算并输出1—20中偶数整数的平方根的值.
请高手帮我做做。。急呢~谢谢啦。

1、
set talk off
dimen aa(5)
for i = 1 to 5
input to aa(i)
next
?"排序后"
for i = 1 to 5
for j = i+1 to 5
if aa(i)<aa(j) then
t = aa(i)
aa(i) = aa(j)
aa(i) = t
endif
next
??aa(i)
next
set talk on
return

2、
set talk off
for i = 2 to 20 step 2
?i,"的平方根为",sqrt(i)
next
set talk on
return
