How do I interpret this pseudo code and what would it display if ran?

define function main_program() {
    set tmp_array to [69, 32, 116, 110, 101, 108, 108, 101, 99, 120, 69];
    // with tmp_array[1] = 69, tmp_array[2] = 32, etc.

    set counter to the number of entries in tmp_array; 
    run foo(tmp_array, counter);
}

define function foo(a_data_array, a_counter) {
    if (a_counter is equal to or more than 1) then {
        display the character for ASCII code value a_data_array[a_counter];
        do foo(a_data_array, a_counter - 1);
    }
    else if (a_counter is equal or less than 0) then
    {
        display "45A!";
        stop the program;
    }
}

run main_program()
