how to get the value from the array randomly

[gorgeous yayuan geng]

Dear Sihua,

c = random(a(1), a(4)) . I think this code is the reason. You originally
want to get a random number from 6,3,7,2,which is in the array a, but your
code is to select a value randomly from 6 to 2, which means you get a
random value from 2,3,4,5,6. and I wonder if you can successfully complie
the code since random function needs the first parameter as min, the second
parameter as max.
so I would recommend that you get a random value from 1,2,3,4 .I'd better
give you codes:
t=random(1,4)
c=a(t);
s=random(1,3)
d=b(s)
