Many thanks.
You will find the ord() function useful: control characters all have ord(c) < 32. You can also use the chr() function to return a character whose ord() is a specific value, and you can use hex escapes to include arbitrary control characters in string literals: myString = "\x00\x01\x02" regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC www.holdenweb.com PyCon TX 2006 www.python.org/pycon/ -- http://mail.python.org/mailman/listinfo/python-list
