RPN: The Automatic Memory Stack
1.
Lifts the stack
2.
Lifts the stack and replicates the X–register.
3.
Overwrites the X–register.
4.
Clears
x
by overwriting it with zero.
5.
Overwrites
x
(replaces the zero.)
The LAST X Register
The LAST X register is a companion to the stack: it holds the number that was in the
X–register before the last numeric function was executed. (A numeric function is an
operation that produces a result from another number or numbers, such as
.)
Pressing
returns this value into the X–register.
This ability to retrieve the "last x" has two main uses:
1.
Correcting errors.
2.
Reusing a number in a calculation.
See appendix B for a comprehensive list of the functions that save
x
in the LAST X
register.
