Problem Statement

This task is about arrays. For hashes or associative arrays, please see Creating an Associative Array. For a definition and in-depth discussion of what an array is, see Array.

Show basic array syntax in your language. Basically, create an array, assign a value to it, and retrieve an element   (if available, show both fixed-length arrays and dynamic arrays, pushing a value into it). Please discuss at Village Pump:   Arrays.
Please merge code in from these obsolete tasks:

Let's start with the solution:

set ary {}

lappend ary 1
lappend ary 3

lset ary 0 2

puts [lindex $ary 0]

puts $ary; # Print the whole array
