2.

Press the number keys of the applicable register address (00 through 99).
Addresses must be 2 digits, e.g., 01, 02, or 50.



For example, to recall the distance to Andromeda’s Great Spiral
stored in register R12:


RCL _ _

2,200,000.0000

0.0000



Recalling a number into the Xregister causes the stack contents to lift.
That is, previous X value is lifted into the Yregister, the previous Y
into the Zregister, the previous Z into the Tregister. The previous
value in the Tregister is lost off the top of the stack.


Storing and Recalling in Stack Registers


Using the HP41C, you can even store and recall numbers into and from the
stack and LAST X registers. All you have to do is press
· (decimal point) and X, Y, Z, T, or
L (for LAST X) as the register address. When the HP41C prompts you for the
address, simply press the associated letter key (X, Y, Z, T, or L)—there
is no need to enter ALPHA mode. For example, to store the number 19 into the
Zregister of the stack:


19 _

STO _ _

STO ST _

19.0000

0.0000



Now, recall the value from the Zregister:
