Re: How to modify 'write-file'

["richard.christensen" <richard.christensen@avagotech.com>]

Hi Pascal,

I am sorry for being thick.  I have tried several things and have
tried to do some
reading about how to implement this code.  I can't get anything to
work. I can
see what appears to be the correct words on the minibuffer, but upon
hitting enter,
either nothing happens or I get an error about wrong number of
arguments.

Should I be doing this (defun write-file (arg) or should I be creating
a new function?
I see that a list is created but I am sure the write-file does not
want the "Write file:" text
to be part of the operation.  So, some how I need to re-direct the
path and file name from the list
back to the write-function.  Am I missing anything else?

Richard.
