Here is what I'm trying to do :

void main()     {
        int[2][] nam;

        readf(" %d", &num);
        nam.length = num;
        foreach(nim; 0..num)    {
                readf(" %d %d", &nam[0][num], &nam[1][num]);

        }
}


In addition to Adam:
there are typos (num instead of nim) - since num is the array 
length and the indices are 0-based, num is out of bounds...

        foreach(nim; 0..num)    {
                readf(" %d %d", &nam[nim][0], &nam[nim][1]);
        }
        foreach(nim; 0..num)    {
                writef(" %d %d\n", nam[nim][0], nam[nim][1]);
        }
works fine.
