What are the components of the array? A record:

type Three_Values is record
    First  : Integer;
    Second : Integer;
    Third  : Integer;
end record;

type Three_At_Each is array (Positive range <>) of Three_Values;

An array:

type Three_Values is array (Positive range 1 .. 3) of Integer;

type Three_At_Each is array (Positive range <>) of Three_Values;

Or are you using a 2D array:

type Two_D is array (Positive range <>, Positive range <>) of Integer;

type Three_At_Each (Num_Rows : Positive) is record
    Value : Two_D (1 .. Num_Rows, 1 .. 3);
end record;

Or something else I haven't thought of?
