	53	+
	54	+The names of your variables are restricted to some constraints:
	55	+* It must only contain the standard letters (a-z and A-Z), digits (0-9), and underscore (\_ ),
	56	+* It has to begin with a standard letter (a-z or A-Z),
	57	+* It must not be equal to a predefined constant or function (see [expression syntax](Expression-Syntax-For-Generic-Applets.md))
	58	+
	59	+It is not excluded that other names may also work, but it is highly recommended to stick to the constraints given above.
	60	+
	61	+Variable names are case sensitive, e.g.

	63	+\begin{variables}
	64	+ \number{a}{12}
	65	+ \function{A}{a+2}
	66	+\end{variables}
