Note:
• You can change the name of a local variable by overwriting it in the VAR
menu. The cursor appears when

• 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
