SYNTAX

(print  <expr>  [ <destination> ] )
        <expr>          -       an expression
        <destination>   -       an optional destination - must be a file pointer
                                or stream, the default is *standard-output*

DESCRIPTION

The PRINT function prints the <expr> to the specified <destination>. The <expr> is printed followed by a new-line. If <expr> is a string, it will be printed with quotes around the string. The <expr> is returned as the result. The <destination> may be a file pointer or a stream. If there is no <destination>, *STANDARD-OUTPUT* is the default.

EXAMPLES

(print 'a)                              ; prints  A     with <NL>
(print '(a b))                          ; prints  (A B) with <NL>
(print 99)                              ; prints  99    with <NL>
(print "hi")                            ; prints  "hi"  with <NL>
                                        ;
(setq f (open "f" :direction :output))  ; create file
(print "hi" f)                          ; returns "hi"
(print 727 f)                           ; returns 727
(print "ho" f)                          ; returns "ho"
(close f)                               ; file contains "hi"<NL>
                                        ;               727<NL>
                                        ;               "ho"<NL>

COMMON LISP COMPATIBILITY: Common LISP specifies that print operations with a <destination> of NIL, will go to *STANDARD-OUTPUT*. XLISP does not send the output to *STANDARD-OUTPUT* with a <destination> of NIL. Common LISP also specifies that a <destination> of T will be sent to *TERMINAL-IO*. XLISP does not allow T as a valid argument for <destination>.
