Given a whole number 0, 1, 2, ... and a sequence of items, the switch command returns the nth item in the sequence.

The first item is in position 0, the second in position 1, and so on.

For example, switch(rint(5), 2, 3, 5, 7, 11) returns a random choice from the first 5 primes.

$\mathrm{MapleTA}:-\mathrm{Builtin}:-\mathrm{switch}\left(1\,''red''\,''green''\,''yellow''\right)$

The MapleTA[Builtin][switch] command was introduced in Maple 18.
