If you have a list, say {10,20,30}, you can Sto> it in L1 (or any list variable). Then each item in the list is accessible by its index.

In this example L1(2) would return 20. And the list would stay easily accessible(even in CAS environment). Consequently let your program return the result as a named list, of which you then have full control.
