set!

Usage

set!(a, n, x)
a.n := x;

Signature

set!:

(%, MachineInteger, T) $\to$ T

Parameter	Type	Description
a	%	a linear structure
n	MachineInteger	an index
x	T	an entry

Description

Sets the element of $a$ with index $n$ to $x$ and returns $x$. The position of that element depends on the indexing scheme of each actual type, for example if it is $0$-indexed, then $a.n := x$ sets the ${(n+1)}^{{\rm st}}$ element of $a$, while if it is $1$-indexed, then $a.n := x$ sets the ${n}^{{\rm th}}$ element of $a$.

Remarks

Bound checking depends on the actual type, some perform it and some do not.
