Check the new contents of variable

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 followed by the variable’s soft menu key. For example, in RPN, if we
want to change the contents of variable
z1
to ‘
a+b
⋅
i
’, use:
³~„a+~„b*„¥`
This will place the algebraic expression ‘
a+b
⋅
i
’ in level
1:
in the stack. To
enter this result into variable
z1
, use:
J„
@@@z1@@
To check the new contents of
z1
, use:
‚
@@@z1@@
An equivalent way to do this in Algebraic mode is the following:
~„a+~„b*„¥` K
@@@z1@@
`
To check the new contents of
z1
, use:
‚
@@@z1@@
Using the ANS(1) variable (Algebraic mode)
In Algebraic mode one can use the ANS(1) variable to replace the contents of
a variable. For example, the procedure for changing the contents of
z1
to
‘
a+bi’
is the following:
„î K

`
. To check the new
contents of
z1
, use:

Copying variables
The following exercises show different ways of copying variables from one
sub-directory to another.
Using the FILES menu
To copy a variable from one directory to another you can use the FILES menu.
For example, within the sub-directory {HOME MANS INTRO}, we have
