Insert Command

Insert( <Object>, <List>, <Position> )

Inserts the object in the list at the given position.

Insert(x^2, {1, 2, 3, 4, 5}, 3) places x2 at the third position and creates the list {1, 2, x2, 3, 4, 5}.

If the position is a negative number, then the position is counted from the right.

Insert(x^2, {1, 2, 3, 4, 5}, -1) places x2 at the end of the list and creates the list {1, 2, 3, 4, 5, x2}.

Insert({11, 12}, {1, 2, 3, 4, 5}, 3) places the elements of the first list at the third (and following) position(s) of the second list and creates the list {1, 2, 11, 12, 3, 4, 5}.

If the position is a negative number, then the position is counted from the right.

Insert({11, 12}, {1, 2, 3, 4, 5}, -2) places the elements of the first list at the end of the second list before its last element and creates the list {1, 2, 3, 4, 11, 12, 5}.
