To store a value in a list, connect the variable you want to store the list at, and an index at which to store the value to a [[List Element]], then attach the output of List Element and a value to be stored to [[Set Reference]]. | To store a value in a list, connect the variable you want to store the list at, and an index at which to store the value to a [[List Element]], then attach the output of List Element and a value to be stored to [[Set Reference]]. | ||

* The index ranges from 0 to 1,048,575, attempting to access a list at a higher index will result in a "List too big!" error. Negative indices return the default value, and cannot be overwritten. | * The index ranges from 0 to 1,048,575, attempting to access a list at a higher index will result in a "List too big!" error.
