• You do not need to enter an alphabetic character. Just specify the
named local variable using a number from 0 to 8, or move the arrow
to the appropriate variable the press e.
5. Press @ v 0 e.
• The value of VAR 0 will be recalled.
• Alternatively you can recall a variable by
moving the arrow to it then press e
twice.
Note:
• You can change the name of a local variable by overwriting it in the VAR
menu. The cursor appears when r is pressed in the VAR menu.
• Local variables not stored using the filing equations function will be
deleted by mode selection or memory clear operation (@ P
1 y).
• Local and global variables will be cleared by creating a new program,
and editing and running a program.
Using variables in an equation or a program
Both global and local variables can be used directly in an equation or a
program. Local variables are useful when you need to use variables such as
X
1 and X 2 at the same time in another equation. The local variable names
and their values can be saved in each equation. (See page 58.)
Example
Using A (6) and A 1 (0.0000125) from the last two examples, solve the
expression.

—
A 1
– 1000A
1. Press j 1 k.
• Start entering the expression.
2. Press @ v.
3. Press 0 - 1000 ; A e.
• The display returns automatically to the
previous screen after you have chosen
the local variable, and you can continue
to enter the expression.
• You do not need k if you use a
variable. However, the variable must be
a multiplier.
