- POV-Ray allows you to define identifiers for later use in the file. An
- identifier may be 1 to 40 characters long. It may consist of upper or lower
- case letters, the digits 0 through 9 or an underscore character. The first
- character must be an alphabetic character. The declaration of identifiers
- is covered later.
-
- POV-Ray has a number of reserved words which are used in the language.
- All reserved words are fully lower case. Therefore it is recommended that
- your identifiers contain at least 1 upper case character so it is sure to
- avoid conflict with reserved words. The following keywords are reserved in
