When attempting to produce an ampersand character (&) at runtime, it is necessary to write an extra character (&&). This is intended behavior because E-Prime uses the ampersand internally in script operations.
For example, a TextDisplay that states "dogs & cats" should be stated as "dogs && cats" to display the ampersand character correctly. If the extra ampersand is not specified, the example would appear as "dogs _ cats".
