How does one go about removing the first element of a list
Have a look to the LIST command, you'll have everything you need.
LIST
List operations.
LIST(LENGTH <list> <output variable>)
LIST(GET <list> <element index> [<element index> ...] <output
variable>
)
LIST(APPEND <list> <element> [<element> ...])
LIST(INSERT <list> <element_index> <element> [<element> ...])
LIST(REMOVE_ITEM <list> <value> [<value> ...])
LIST(REMOVE_AT <list> <index> [<index> ...])
LIST(SORT <list>)
LIST(REVERSE <list>)
LENGTH will return a given list's length.
GET will return list of elements specified by indices from the list.
APPEND will append elements to the list.
INSERT will insert elements to the list to the specified location.
When specifying an index, negative value corresponds to index
from the
end of the list.
REMOVE_AT and REMOVE_ITEM will remove item from the list. The
difference is that REMOVE_ITEM will remove the given items, while
REMOVE_AT will remove the item at the given indices.
