I think the % expansion is what he is looking for.  Assuming you have written
the file recently or have autowrite on, :! program % >%.ext would do
what you ask (although if you have modified the file and want to make a
backup copy of the original like this, having autowrite enabled will kill
you).  If you want to get the filename into the editor buffer, you could
use :r !echo %.
I often go to the end of a c program file and use :r !lint % to check for
errors, using the === that lint emits as a marker between the text and
the error list.  Perhaps not as nice as multiple windows, but it works.
