RE: Having the prolog buffer in a different frame.

["Drew Adams" <drew.adams@oracle.com>]

    I'm using prolog mode (prolog.el) and it works well, but there is one
    little issue that bugs be.  If I choose "Consult" a file, region or
    buffer, it compiles and evaluates and opens a new prolog session with
    the new predicates taken in mind *within* the current frame.  I like to
    have two frames, though, with the prolog session next to the
    one editing
    the predicates.

    Basically, I would like to tell Emacs, that if there already is
    a prolog
    session (buffer) running in a different frame, it should not open a new
    view of this in the current frame.

    How? :)

Try setting `pop-up-frames' to `t'. Otherwise, check the doc for prolog-mode
(`C-h m' when you're in prolog mode) to see if there is a specific option
for this. Try also `M-x apropos RET prolog'.
