To get a different list of the same type:
1. Press
. . . The GET menu contains a menu label for each
named list of that type (see figure 7-1), plus
1IiID9I .*
2. Press the appropriate menu key. Pressing
IIiID9I
displays a new,
empty list.
Figure 7-2 illustrates switching between two number lists named
JANCHECKS and FEBCHECKS, creating a new list, and naming that
list. Notice that you cannot switch from a nameless list. If your cur-
rent list contains numbers and is nameless, pressing a menu key in
the GET menu displays:
CURRENT LIST UNNAMED;
NAME OR CLEAR THE LIST
and the HP-18C returns to the previous menu. To name the list, press
1mliIII .
To clear the list, press

If pressing
IEIiII
causes the HP-18C to display the message I NSUFF I C I ENT MEMORY
and an abbreviated GET menu (there will be only one menu label and no
IiIIID
label), you
should exit the GET menu, complete any arithmetic (calculator line) calculations you were in
the process of doing (press

and then try pressing
IEIiII
again. If there is
still insufficient memory to display the entire GET menu, the HP-18C displays one menu
label (list name). If this is not the list you want, press the menu key and then press
IEIiII
again to display another list name. Continue this procedure until you've switched to the
desired list.
