how to get the value from the array randomly

[sihua xu]

Hello everyone 

  I know how to define the array with the help of David and sally, and I get the value randomly according to way that they told me, but actually,  I found the program do not get the value of the array randomly and i do not know the reason.

I want to achieve the purpose of the following

 to get one value from each array and decide to end or continue the program by comparing the size of the value from the two arrays. the script example  just as follows

dim a(1 to 4) as integer

dim b (1 to 3) as integer

dim c as integer

dim d as integer

dim randompik as integer

a(1) = 6

a(2) = 3

a(3) = 7

a(4) = 2

b(1) = 2

b(2)= 6

b(3) = 4

c = random(a(1), a(4))

d = random(b(1), b(3))

if c>d then 

 randompik = 1

else randompik =2

end if

I would be grateful if anybody could help me to find the reason why it can not achieve my purpose and modify that

thanks

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)

I will just add that you can find documentation for the random()
function in the E-Basic Help facility.
