Please forgive me for sticking my neck out, but other RISC OS apps get
B and I right, even when they map to strange things like
'xxx.yyy.Condensed.Black.Oblique'.
My understanding of RISC OS font names is as follows:
Normal = N or N.X
Bold = N.B
Italic = N.I or N.X.I
Bold Italic = N.B.I or N.I.B
where
N = (eg) '<Font$Path>Times' or '<Font$Path>Times.Condensed'
X = 'Medium', 'Regular', 'Roman' or 'Book'.
I = 'Italic', 'Oblique' or 'Inclined'.
B = 'Bold', 'Black', 'Demi', 'Heavy', 'Extra' or 'Ultra'
or something which contains one of these (eg 'SemiBold')
but not 'xxxLight' (eg 'UltraLight').
Thus, surely a program only needs to consider the last 2 elements of a
pathname when deciding which of the 4 variants a fontname represents? It
also needs to know what N is, even when B and/or I are selected, and must
take X into account when it exists.

A program has a choice in this instance because:
if N = 'Hull' then B = 'Hull.Black' and I doesn't exist.
if N = 'Hull.Black' then I = 'Hull.Black.Oblique' and B doesn't exist.
if N = 'Hull.Light' then I = 'Hull.Light.Oblique' and B doesn't exist.
Whichever one is chosen, it should be able to switch between N, B and I
logically. It would also be possible, of course, to devise a method to
recognise all 4 variants sensibly ('Light' being interpreted as 'Medium'
in this case).
If John wants to use B and I to select all Hull variants in OP as things
stand, 'Hull.Light' and 'Hull.Light.Oblique' must be renamed. But this
isn't as simple as it might appear - I can do it for you, John, if you
care to send me me your entire Hull font directory.)
