nthelem

nthelem( 
x_index1 
l_list 
) 
=> g_result / nil

Returns the indexed element of the list, assuming a one-based index.

Thus nthelem(1 l_list) is the same as car(l_list).

x_index1	Index of the element of l_list you want returned.
l_list	List of elements.

g_result	The x_index1 element of l_list.
`nil`	If x_index1 is less than or equal to 0 or is greater than the length of the list.

nthelem( 1 '(a b c) )  
=> a

z = '(1 2 3)
nthelem(2 z)           
=> 2
