Restoring the Last Stack (UNDO)

(r^f UNDO

) restores the stack to the way it was

before you executed the most recent command.

To restore the stack to its previous

state:

■ Press ff^(UNDO).

The Interactive Stack

The normal stack display is a “window” that shows level 1 and as
many higher levels as will fit in the display. The HP 48 also features
the Interactive Stack, a special environment in which the keyboard
is redefined for a specific set of stack-manipulation operations. The
Interactive Stack lets you do the following:

■ Move the window to see the rest of the stack.
■ Move and copy objects to different levels.

■ Copy the contents of any stack level to the command line.

■ Delete objects from the stack.
■ Edit stack objects.
■ View stack objects in an appropriate environment.

When you activate the Interactive Stack, the stack pointer turns on

(pointing to the current stack level), the keyboard is redefined, and

the Interactive Stack menu is displayed. You must exit the Interactive
Stack before you can execute any other calculator operations.
