Hi Eddie,

That diminished chord is usually going to be a diminished seventh chord in BiaB, rather than just a triad. If you would rather have a half diminished seventh chord then you could enter dm7b5.

There are shortcuts too. D = diminished. H = half diminished. See the list of supported chords http://www.pgmusic.com/tutorial_chordlist.htm

I searched the PG site for something like the dm5b you said was from the FAQ -- I see that the flat is only after the 5 when the chord is major or dominant.
