How to: Move Data Into and Out of a Variable 

You store a value in a variable by putting the variable name on the left side of an assignment statement.

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 variable counter 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.
