write-string string &optional output-stream &key start end => string
write-line string &optional output-stream &key start end => string
Arguments and Values:
output-stream -- an output stream designator. The default is standard output.
start, end---bounding index designators of string. The defaults for start and end are 0 and nil, respectively.
write-string writes the characters of the subsequence of string bounded by start and end to output-stream. write-line does the same thing, but then outputs a newline afterwards.
(prog1 (write-string "books" nil :end 4) (write-string "worms")) >> bookworms => "books" (progn (write-char #\*) (write-line "test12" *standard-output* :end 5) (write-line "*test2") (write-char #\*) nil) >> *test1 >> *test2 >> * => NIL
Side Effects: None.
Exceptional Situations: None.
write-line and write-string return string, not the substring bounded by start and end.
(write-string string) == (dotimes (i (length string) (write-char (char string i))) (write-line string) == (prog1 (write-string string) (terpri))
