Putting Data in a Variable
To store a value in a variable
Use the variable name on the left side of an assignment statement.
The following example sets the value of the variable
alpha
.alpha = (beta * 6.27) / (gamma + 2.1)
The value generated on the right side of the assignment statement is stored in the variable.
Getting Data from a Variable
You retrieve a variable's value by including the variable name in an expression.
To retrieve a value from a variable
Use the variable name in an expression. You can use a variable anywhere you can use a constant or a literal, except in an expression that defines the value of a constant.
-or-
Use the variable name following the equal (
=
) sign in an assignment statement.The following example reads the value of the variable
startValue
and then uses the value of the variablecounter
in an expression.counter = startValue cellValue = (counter + 5) ^ 2
The value of the variable participates in the expression just as a constant would, and then it is stored in the variable or property on the left side of the assignment statement.
