You are right Ben,
For braces, I wanted to change e.g. :

func() {
body; }

to:

func()
{
body;
}

Marc Jessome suggested "http://astyle.sourceforge.net/" for this job and
it works like a charm for all possible brace combinations. It's not a
tool I knew of.

Thanks Marc.

Now for comments, I want to change:

// Comment1
// Comment2

to:

// Comment1
// Comment2
where I can specify ---------^ this column.
(Long source code lines wuill 'push' this to the right)

(Format might get mangled by mail/list) :=)

Yes thanks, that is exactly why I want to convert the files.
I find the older styles harder to ascertain the logical flow in. (Just
my preference).

Many thanks to all,

Bob
