I'm not really sure what you mean. I suppose the "8va basso - - - - - - "
indication that is found on some piano scores, which denotes that a
certain number of notes are to be played an octave lower.
Abcm2ps doesn't have this indication, but it's really easy to add it using
the existing "8va" new decoration (see deco.abc) as template. Try this:
% octava.abc -*- Abc -*-
%
% This file provides a few decorations for abcm2ps

Needless to say, abc2midi will not be able to use these new decos.
If this is what you meant, I'm happy.
