Answer:

Rules for Naming Variables

1 A variable name must be of the form $name or ${name}.

2 The string name can consist of letters (a-z and A-Z), numbers (0-9), and underscore characters (_).

3 The first character of name must be an alphabetic character (a-z or A-Z).

4 If the ${name} form is used, spaces can also appear in name.
