How to pick more than one value from an array?

Here is what I need to do. I have an array of lets say 10 items and I want to pick three different items.
For one item I would use something like:
int pickitem = duniform(1,10);
int selectitem = samplearray[pickitem]

I tried to use a 'for' loop and tried to store the 3 selected values in a new array. For example:

doublearray selecteditems = makearray(3);
for (int index = 1; index <= 3; index++)
{
int pickitem = duniform(1,10);
selecteditems[index] = pickitem;
}

The problem I face is that there is no way I could think of to make sure that pickitem variable gets a new value for each value of index.

Hi,

you can choose you items indirectly from for example from table. In this table you store the references to the item. Each time you choose a row, you copy the reference to your array and delete this row from the table. Next time you choose again the range of the duniform function is reduced: duniform(1,gettablerows(table),random stream)
