( i * n +n -- ) ( R: -- j * x +n )
Remove n+1 items from the data stack and store them for later
retrieval by NR>. The return stack may be used to store the
data. Until this data has been retrieved by NR>:
this data will not be overwritten by a subsequent invocation of
a program may not access data placed on the return stack before
the invocation of N>R.
An implementation may store the stack items in any manner. It may
store them on the return stack, in any order. A stack-constrained
system may prefer to use a buffer to store the items and place a
reference to the buffer on the return stack.
