Next, we will create a sub-directory named INTRO (for INTROduction), within
MANS, to hold variables created as exercise in subsequent sections of this
chapter. Press the
$
key to return to normal calculator display (the TOOLS
menu will be shown). Then, press
J
to show the HOME directory contents
in the soft menu key labels. The display may look like this (if you have
created other variables in the HOME directory they will show in the soft menu
key labels too):
To move into the MANS directory, press the corresponding soft menu key
(
A
in this case), and
`
if in algebraic mode. The directory tree will be
shown in the second line of the display as
{HOME MANS}
. However, there
will be no labels associated with the soft menu keys, as shown below,
because there are no variables defined within this directory.
Let’s create the sub-directory INTRO by using:
„¡

˜ ~~intro`
@
@CHK@@

Press the
$
key, followed by the
J
key, to see the contents of the MANS
directory as follows:
Press the
)!INTRO
soft menu key to move into the INTRO sub-directory. This will
show an empty sub-directory. Later on, we will do some exercises in creating
variables.
Using the command CRDIR
The command CRDIR can be used to create directories. This command is
available through the command catalog key (the
‚N
key, second key in
fourth row of keys from the top of the keyboard), through the programming
menus (the

key, same key as the
‚N
key), or by simply typing it.

soft menu key to activate the
command.
