Unquoted Strings

Where a series of characters cannot be parsed as a decimal number, they are interpreted as a simple string composed of one word. This word is delimited by spaces, or by other tokens, such as ) in conditional expressions.

This unquoted text is interpreted as simple strings and are generally equivalent to placing the string in single quotes.

The interpretation of the text depends on the context, which is usually defined by an attribute which has a data type.
