The points with an $$ x $$-coordinate of 4 that are 10 units away from the point $$ (-2, -1) $$ can be found as follows:

1. Let the point be $$ (4, y) $$.
2. Use the distance formula:
   $$
   \sqrt{(4 - (-2))^2 + (y - (-1))^2} = 10
   $$
3. Simplify the equation:
   $$
   \sqrt{6^2 + (y + 1)^2} = 10
   $$
   $$
   36 + (y + 1)^2 = 100
   $$
4. Solve for $$ y $$:
   $$
   (y + 1)^2 = 64
   $$
   $$
   y + 1 = \pm 8
   $$
   $$
   y = 7 \quad \text{or} \quad y = -9
   $$

Therefore, the required points are $$(4, 7)$$ and $$(4, -9)$$.

**Answer:** $$ (4,7),\ (4,-9) $$
The points are (4,7) and (4,-9).
