A Defaults file consists of statements. Each statement is on a seperate line. A statement may be split over several lines by preceeding the newline with a backslash (\). The exclamation mark (\!) is the line-comment character. All input from a ! upto the following newline is replaced by a single space-character. Empty lines or lines containing only blank space are ignored.

Default files may include other default files using the statement

• include <file> Default statements are of the form:

  <class>.<class-variable>: <value>

  Where <class> denotes the name of the class, or * to indicate the default applies for any class defining this class-variable. If both forms are found, the statement with the explicit class-name is used. <class-variable> denotes the class-variable name. <value> is the default value of the class-variable. The syntax for <value> is similar to the arguments of send/[2-12]. The (informal) syntax for <value> is below.

  <Any>	:= <int>
                   | <float>
                   | <Name>
               | @<Name>
                   | <Chain>
                   | <Object>
  
  <Chain> := [ <Any> {, <Any>} ]
               | [ {<Blank>} ]
  
  <Object> := <ClassName>()
                | <ClassName>(<Any> {, <Any>})
                    | <PrefixOp> <Any>
                    | <Any> <InfixOp> <Any>
                    | <Any> <PostfixOp>
                | "<String>"
  
  <String> := {<CharNotDoubleQuote>|""}
  
  <Name>	 := <Letter>{<Letter>|<Digit>}
                    | '{<CharNotSingleQuote>|''}}'
