Hi,
X = Table[Random[], {10}, {12}];
Y = X; Y[[All, 8]] = "red"; Y[[All, 11]] = Y[[All,
9]] + 1;

| Hello Everyone,
|
| If I have an n x m array called X, how can I
create another
| array, Y, whose rows are those rows in X whose
8th column contains
| the word "red" and whose 11th column is a number
greater than 9?
