write-string, write-line [Function]

write-string string {&optional output-stream {&key} start end} => string

write-line string {&optional output-stream {&key} start end} => string

Arguments and Values::

string---a string.

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.

Description::

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.

Examples::

 (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

Affected By::

*standard-output*, *terminal-io*.

Notes::

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))
