Restrictions on Property Names
All property names must follow these restrictions.
- A property name is an Identifier, which is a text string that must begin with either a letter or an underscore. Identifiers and property names may contain letters, numerals, underscores, or periods; but cannot begin with a numeral or period.
- Public property names cannot contain lowercase letters.
- Private property names must contain some lowercase letters.
- Property names prefixed with % represent system and user environment variables. These are never entered into the Property table. The permanent settings of environment variables can only be modified using the Environment Table.
