hm

I love Java.


public class Speciaal
{

public static void main(String[] args)
{
for(int x=0; x<10; x++)
{
for(int i=0; i<10; i++)
{
for(int k=0; k<10; k++)
{
for(int l=0; l<10; l++)
{
System.out.print("&#"+x+i+k+l+"; ");
}
}
System.out.println(" ");
}
}
}

}

(another reason to use (the better and (way) more (if not extremely) convenient programming language) lisp (which stands for (if I recall correctly) list processing) jajajaj.)

Code:

(with-open-file ("out.txt" out :direction :output)
    (dotimes (i 10000)
        (format out "&#~4,'0d; " i)
        (if (zerop (mod i 10))
            (format out "~%"))))
