list.at

Syntax

a := list.at(l,i) := a

Get/sets the value of a line at index i.

This is occasionally useful instead of using an argument because it is compatible with splitting -

for example to return the 4th entry in a list of lists and return that as a list.

Note also that currently negative indices or an index range are not supported.

Since the first argument is in implicity reference, it cannot be a temporary. An intermediate local or global value must be created if this is called in an extended expression.

Returns:a - the value in list l at index i. Accepts:a - the value placed list l at index i. Arguments:al - the list to get/set i - the index of the list to retrieve
