non repeating array

How would you go about creating an array that would not repeat results?
example:
I want 15 different results from
aTrait: array [1..100] of string =

thanks

    What do you mean by 15 different results? If you want 15 different arrays with 100 string elements, you can either create 15 different array variables, or a 2-D array with in the second dimension 15 elements.

    Your giving me way too much credit. Just a simple 1-D array of 100 string elements all pertaining to colors (from white to black). I input that I want 15 colors from that array. What I want to see is 15 different colors spit out into a memobox.
    example: white, red, blue, black, green, yellow, pink, etc .
    not: red, red, blue, green, pink, red, puse, etc.
    Thanks

    The trick here is to fill a 15-element array in such a way they you check each element to be added with all previous elements. Here is a simple example:
    [code]
    var
    ColorToBeAdded: string;
    ColorsArray: array[1..15] of string;
    NumColor: integer;
    i: integer;
    FoundColor: boolean;
    begin
    // Example Initializion: Run only once
    NumColor := 0;
    ColorToBeAdded := 'red';
    // Start of "real example code"
    FoundColor := False; // Assume the color isn't in the list
    if NumColor > 0 then // Check if there are already some added
    for i := 1 to NumColor do
    if ColorToBeAdded = ColorsArray[i] then
    FoundColor := true; // Found a matching color
    if not FoundColor then // Add the new color
    begin
    inc(NumColor);
    ColorsArray[NumColor] := ColorToBeAdded;
    end;
    end;
    [/code]
    This code will add the color red to the array. If you run the "real example code" twice with red as color, you will find only 1 element is filled, and NumColor is still 1. Only if you add a non-red color, it will be added.
