(pretty-print 100)

(while (> (set 'sofar (read-buffer infile 'buff 16 )) 0)
(if (< sofar 16 ) (dotimes (x (- 16 sofar)) (set 'buff (append buff (char 0)))))
(dolist (x (explode buff)) (print (format "%02X " (char x))))
(dolist (x (explode buff)) (unless (and (>= (char x) 32) (<= (char x) 126)) (print ".") (print x)))

(close infile)
(println "Done")

Actually (pretty-print 100) is not necessary in your program. Pretty print only controls the printing of expressions when doing 'save' or 'source' pretty-print formatting expressions.

I'll also include in: http://www.newlisp.org/norman-5-cent.txt

Hello Lutz,

I need pritty-print in my X-windows terminals otherwise i always get the
default from the nelwisp-realine IO when executing newlisp scripts...

The syslog example also has it where it prints direclty from a buffer,
if i dont use pritty-print there i.e. then the output gets messed-up...
