If you use Firebird 1.5 (It should work on higher versions too), you can use this simple function i made to convert a single string into an integer array:

create or alter procedure INTEGER_LIST (
    input varchar(4096))
returns (
    INT_VALUE integer)
as
declare variable CHAR_COUNT integer;
declare variable PARAM_LENGTH integer;
declare variable READ_VALUE char(1);
declare variable CURRENT_INTEGER varchar(20);
begin
    param_length = strlen(input);
    char_count = 0;
    current_integer = '';
    while (char_count < param_length) do begin
        char_count = :char_count + 1;
        read_value = substr(:input, :char_count, :char_count);
        if (:read_value <> ',') then begin
            current_integer = :current_integer || :read_value;
        end else if (:read_value <> ' ') then  begin
            int_value = cast(:current_integer as integer);
            current_integer = '';
            suspend;
        end

        if (:char_count = :param_length) then begin
            int_value = cast(:current_integer as integer);
            suspend;
        end
    end
end

Usage

select int_value from integer_list('1,2,3,4, 5, 200, 1, 598415, 2')

Will return this:

INT_VALUE
1
2
3
4
5
200
1
598415
2
