Notice that this time the contents of program p1 are listed in the screen.  To see 
the remaining variables in this directory, press L:

Listing the contents of all variables in the screen
Use the keystroke combination ‚˜ to list the contents of all variables in the 
screen.  For example:

Press $ to return to normal calculator display.

Replacing the contents of a variable can be thought of as storing a different 
value in the same variable name.  Thus, the examples for creating variables 
shown above can be used to illustrate the replacement of a variable’s content.

Using as illustration the six variables, p1, z1, R, Q, A12, a, and A, created 
earlier, we will proceed to change the contents of variable A12 (currently a 
numerical variable) with the algebraic expression ‘

β/2’, using the STO

command.  First, using the Algebraic operating mode:

³~‚b/2™ K 

@@A12@@  `

Check the new contents of variable A12  by using ‚

@@A12@@  .

Using the RPN operating mode:

³~‚b/2`  ³

@@A12@@  ` K

or, in a simplified way, 

³~‚b/2™  ³

@@A12@@   K

Using the left-shift „ key followed by the variable’s soft menu key (RPN)
This is a very simple way to change the contents of a variable, but it only works 
in the RPN mode.  The procedure consists in typing the new contents of the 
variable and entering them into the stack, and then pressing the left-shift key
