1. SIZE
2. L1(<number>) to access further down inside, L1(<number>,<number>...) Ex: L1(2,3) returns 6 in your given list. TW Although I work for the HP calculator group, the views and opinions I post here are my own.

RE: Acces to a list
Hello,
Var[n] refers to: if var is a list: the nth element of the list if var is a string, the nth char of the string if var is a vector, the nth element of the vector if var is a matrix, the nth line of the matrix, or if n<0, the nth column if var is an int, the nth bit of the int. This works both in RCL and STO var[n, m] refers to: if var is a list: var[m] for the nth element of the list (parameter list can be up to 16 long!) if var is a string, m chars starting at index n in the string if var is a matrix, the element at pos n,mx if var is an int, the m bit starting at pos n from the int list(0):=val: adds at the end of the list That should get you started.
