Well Jon, I think you win the prize ;-)

I can't even come close to that in C and i'm sure someone can out do my
feeble attempt.

int main()
{
    int a,b,c,d;
    for ( a=65; a < 91; a++) {
        for ( b=65; b < 91; b++) {
            for ( c=65; c < 91; c++) {
                for ( d=65; d < 91; d++)  {
                    printf("%c%c%c%c\n",a,b,c,d);
                }
            }
        }
    }
}

Have fun,
Harm none.
