Names for objects defined in the Object Dictionary must conform to the following conventions:

• The name can be from 1 to 18 characters in length.

• The name can contain only letters (a-z, A-Z), digits (0-9), dollar signs ($), and underscores (_).

• The name must begin with a letter or a dollar sign.

• Most names must be unique among objects of the same type in the same application directory. (Note that the software is case-insensitive: ABC and abc are the same name.) For more information, see the documentation for your operating system.

• The name does not duplicate words reserved to the software’s use, such as a command or function keyword (CREATE, $isalphabetic).
