That's the ONLY issue? What about searching source code files? What's the regular expression for locating a number with an arbitrary number of digits seperated into an arbitrary number of blocks of an arbitray number of digits with an arbitrary number of whitespace characters between each block? > > -- > Steven -- http://mail.python.org/mailman/listinfo/python-list
