I need help in filling array in Pascal with random number.

I have 9 empty array ( A: array[1..10] of integer ), and i want to fill the array with integer for 1 to 9 randomly, but one number can only be choosen one time. So when a number (eg. 5) was choosen for A[1], then the number should not be choosen again for A[2]..A[9].

Any one can help please!

Thnk you.
