Reviewing the Stack
R (Roll Down)
The
<
(roll down) key
lets you review the entire contents of the stack by
"rolling" the contents downward, one register at a time. You can see each
number when it enters the X–register.
Suppose the stack is filled with 1, 2, 3, 4. (press 1

Pressing
<
four times rolls the numbers all the way around and back to where
they started:

What was in the X–register
rotates
into the T–register, the contents of the T–register
rotate into the Z–register, etc. Notice that only the
contents
of the registers are
rolled — the registers themselves maintain their positions, and only the X– and
Y–register's contents are displayed.
R (Roll Up)
The
º
;
(
roll up
) key has a similar function to
<
except that it "rolls" the
stack contents upward, one register at a time.
The contents of the X–register rotate into the Y–register; what was in the T–register
rotates into the X–register, and so on.
