1: SORTA(
Sorts lists in ascending order.
2: SORTD(
Sorts lists in descending order.
3: DIM

4: SEQ(
Creates a sequence.
Note:
SORTA(
and
SORTD(
are the same as
SORTA(
and
SORTD(
on the
STAT EDIT
menu.
SORTA(
(sort ascending,
LIST OPS
, item 1) and
SORTD(
(sort
descending,
LIST OPS
, item 2) have two uses.
¦
With one list name, they sort the elements of an existing
list and update the list in memory.
¦
With two to six list names, they sort the first list and then
sort the remaining lists as dependent lists, placing their
elements in the same order as their corresponding
elements in the first list. This allows you to keep sets of
related data in the same order when you sort lists.
All of the lists to be sorted must be the same length. The
sorted lists are updated in memory.
Note: You can reference a specific list only once in these
instructions.
