Using Variables In An Equation Or A Program - Sharp EL-5230 Operation Manual

• 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.
Press @ v 0 e.
5.
• 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 and X at the same time in another equation. The local variable names
1 2
and their values can be saved in each equation. (See page 58.)

• 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.
