Use the up arrow key — to select the sub-directory MANS and press @@OK@@. If

you now press „§, the screen will show the contents of sub-directory

MANS (notice that variable A is shown in this list, as expected):

Press $ @INTRO@ `(Algebraic mode), or $ @INTRO@ (RPN mode) to return to

the INTRO directory. Press „¡@@OK@@ to produce the list of variables in

{HOME MANS INTRO}. Use the down arrow key (˜) to select variable R,

then press @@COPY@. Use the up arrow key (—) to select the HOME directory,

and press @@OK@@. If you now press „§, twice, the screen will show the

contents of the HOME directory, including a copy of variable R:

Using the history in Algebraic mode

Here is a way to use the history (stack) to copy a variable from one directory to

another with the calculator set to the Algebraic mode. Suppose that we are

within the sub-directory {HOME MANS INTRO}, and want to copy the contents

of variable z1 to sub-directory {HOME MANS}. Use the following procedure:

‚@@z1@ K@@z1@ ` This simply stores the contents of z1 into itself (no change

effected on z1). Next, use „§` to move to the {HOME MANS} sub-

directory. The calculator screen will look like this:

1 2 ... 112 113 114 115 116 117 118 119 120 121 122 ... 886 887
