my @x; #an empty array
my @y = (); #also an empty array
@x = (1,2); #assigning a list to an array
$x[2] = 3; #assigning an element to an array
           #notice we refer to the array in scalar 
           #context
@y = @x; #assign an array to an array
my @z = ("a","b","c",1,2,"3",1+3,"1"+"3"); #declare array assign list


print ("@x ","@y ","@z ");  #print list
