Changing Appearance of the Variable
A variable can be displayed in three forms. These are:
• Normal Readout: The Normal Readout option displays the name of the
variable and its value on the Stage.

• Large Readout: The Large Readout option displays only the value of
the variable in a larger size than normal readout.

• Slider: The Slider option displays the name and value of the variable,
along with a slider to change the value of the variable. The range of
value for the slider is from 1 to 100.
