 In RPN mode the calculation would be carried out using the following keys: 
  
 Calculate the value and store it in V: 
  
 2*1%)0!!3 
  
 As the value is already on the stack, just calculate its arc sine, then multiply by 5: 
  
 !4*+ 
  
 Next, divide by the arc cosine of the expression, which is recalled from V: 
  
 -3!65...

Answer: The three exchanges swap values in two data registers without affecting an ongoing calculation. Note that 
this works in algebraic and in RPN mode. 
 
Pressing #: displays the A..Z symbol, and any letter from A through Z can be pressed. The value in the chosen 
register is displayed in a message without changing...

The HP 35s and indirect registers 
 
The HP35s contains registers or variables that can be referenced directly or indirectly. Variables A through Z can be 
directly addressed, as in a !# instruction. Indirect addressing uses two of these direct variables as indices 
that hold the location or address where an operation is to be performed. The two variables that are used this...

through 33. On the HP 35s, they are referenced using an index of -27 through -32. On the HP 33s the index register was 
itself referenced by a value of 27. Since the index registers on the HP 35s are the variables I and J, there is no 
specialized index register. 
 
On the HP 35s, the indirect registers are cleared using the CLVARx function, found in the !()menu. Press 
!(*...

Answer: Run the program by pressing 6#7. When the program completes, in RPN mode the last two 
random numbers generated will be shown while in algebraic mode, only the most recent random number 
will be shown in the display. 
 
Example 2: Assuming that indirect registers 1 through 10 contain the random numbers generated in example 1, write a 
short program to sort indirect...

Solution: Jake wrote the program presented below which will display the indirect registers. The program will run in 
RPN mode only. Press +,, and then enter the program below. Press !- and then these 
keystrokes:

The purpose of this training aid is to show how arithmetic can be carried out directly using HP 35s memory registers. 
First, the following is a short explanation of variables and registers; the same information is given in the practice aid on 
using calculator memories. That training aid then gives more information on the various other uses of...
