=COMMAND GetListElement (list int) value
=DESC 
Returns the value at the specified index of a list. Lists are indexed from zero.

If a list is stored in a variable, this can be abbreviated to <-list[<-index].

=CMD
=COMMAND SetListElement (list int value)
=DESC 
Stores a value at the specified index of a list. The previously stored value is overwritten.

If a list is stored in a variable, this can be abbreviated to <-value ->list[<-index].
=ENDDESC

=COMMAND InsertListElement (list int value)
=DESC
Stores a value at the specified index of a list. The previously stored value, and all subsequent values have their indices shifted up by one.
=ENDDESC
=EX

=COMMAND AppendToList (list value)
=DESC
Adds a value to the end of a list.

=CMD
=COMMAND PrependToList (list value)
=DESC
Adds a value to the beginning of a list. Any values previously stored in the list are shifted up by one.

PrependToList( <-list 0)

Adds all values on the stack to the end of a list. The order of the values will be reversed.

=CMD
=COMMAND CopyList (list) list
=DESC
Creates a copy of a list with the same contents. Someone more computer-eloquent explain pass by reference vs. value here. Note that if the list contains other lists, they will not be copied - for that you need DeepCopyList.
=ENDDESC

=CMD
=COMMAND DeepCopyList (list) list
=DESC
Creates a copy of a list with the same contents. Someone more computer-eloquent explain pass by reference vs. value here. If the list contains any other lists, they are also recursively deep copied.
