Precur­seurs

setlocal Enable­Del­aye­dEx­pansion
set i=2
echo %elem{%i%]%
Doesn't give the desired result because it means: show the value of the elem [variable, followed by i, followed by the value of the ] variable. To solve this problem you must use Delayed Expansion: Enclose index variables in percent symbols, and enclose the array elements in exclam­ation marks:
set elem[1­]=First element
set elem[2­]=S­econd one
set elem[3­]=The third one
set i=2
echo !elem[­%i%]!
setlocal Enable­Ext­ensions
