Sets the value of element i1 in list L1 to n1

Elements are indexed starting with zero, so the third element is at index 2. SetListElement can add a new element at the end of a list, if i1 is the value of the next index (3 if the list currently has only 3 elements); however, it is recommended to use AppendToList to add items to the end. Attempting to use SetListElement with an index value greater than the last index +1 does nothing.

#Sets element #3 of list01 to the value of 5
<-list01 2 5 SetListElement

Sample list list01 before:
0 - 100
1 - 105
2 - 110
3 - 115

Sample list list01 after sample command:
0 - 100
1 - 105
2 - 5
3 - 115
