Chapter 2: General Information

•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 0e.

•The value of VAR 0 will be recalled.

•Alternatively you can recall a variable by moving the arrow to it then press e twice.

0.0000125 A1= 0.0000125

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 X1 and X2 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 A1 (0.0000125) from the last two examples, solve 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.
