:Value→Variable

Will store all data on the left side of the arrow into the variable on the right side of the arrow. If a variable can only hold a certain type of data, this function will fail if the wrong data is being placed into the wrong variable (attempting to place a list in Str1 on the TI-84, or a list in y1(x) for example)

Location

• STO (→)

Example

:ClrHome
:5→Y
:Input "NUMBER:",X
:X+Y→Z
:Disp Z

This program will first store 5 in the variable Y. Then it will ask the user for a number and place it in X. It will then add the variables X and Y and store the result in a new variable Z. It will display Z.

Optimized version:

ClrHome
5
Input "NUMBER:",X
X+Ans
Disp Ans

This program stores 5 into internal variable Ans. Then it will ask the user for a number and store it to X. It will then add Ans to X and store it back to Ans. It then displays Ans

Difference to =

= means equals

→ means is

• 1=2 returns a 0 for false (1 equals 2)
• if 2 is saved to variable A
• 1=A returns a 0 for false (1 equals A)
• 2=A returns a 1 for true (2 equals A)
• 1→A saves 1 to variable A (1 is A)
• 2→A saves 2 to variable A (2 is A)
