Stack(In)	Top	Vector
	Top 1	any value x
Stack(Out)		Vector

forms a new vector with x as first element: x [ a b ] | results in [ x a b ]

Stack

Stack	Position	Description
Stack(In)	Top	any value x
	Top 1	Vector
Stack(Out)		Vector

forms a new vector with x as last element: [ a b ] x | results in [ a b x ]

Stack

Stack	Position	Description
Stack(In)	Top	Vector
	Top 1	Vector
Stack(Out)		Vector

merges both vectors into a new vector: [ a b ] [ X Y Z ] | gives the vector [ a b X Y Z ]

Note: If you want to insert only elements into a vector - i.e. you do not necessarily want to create a new vector - the instruction Insert is preferable for reasons of effectiveness.
