Exactly one input field in the sense of StreamDisciplines and Read. FieldS is to be consumed from s . That means that line terminators may not be skipped over and field separators work as delimiters but are to be consumed. This field must be read in completely even if the input does not syntactically conform to the type. But read has to terminate immediately on end of file or in case of errors returned from Streams .
TRUE is to be returned if a value has been read successfully.
Note that read is free to update value instead of creating it if value is non- NIL . This could be of interest if value represents a list or set where subsequent read operations add new elements. If multiple lines are needed, Write. IndentS is to be called on the beginning of each new line. Note that the last line must not be terminated.
