1. Is it possible to modify TeX so, that it uses the Risc OS
   outline fonts ? I want to be able to convert a TeX file to
   something readable without needing the whole TeX font set as
   it takes up lots of space.

2. When using Wimp_GetWindowInfo to read a window block, you also get
   32 bytes for each icon the window contains.  How do you know how
   many icons a window contains ? Note : You can't use the word at location
   84 in the window definition, because when you read that word using
   Wimp_GetWindowInfo you also get the icon blocks ! And you do not know
   the size of the block of memory to allocate... :-(

3. When I use Wimp_GetIconState to read icon data, I can also read icon
   data of non-existing icons.  Why isn't an error generated ? It would be
   nice if the flags would be updated when using XWimp_GetIconState...

4. Has anyone noticed this "bug" in the Morley SCSIFS :
   When clicking on the iconbar icon the root filer window is opened as
   usual, but as a side-effect, the current directory is reset to the root.
   This is very annoying, in particular when running a Task Window which
   is processing files without full pathnames.

   Morley claims that the drive must be mounted each time the user clicks
   on the iconbar.  But ADFS doesn't mount the disc...
   Can anyone shed some light on this.  Is the behaviour of the Morley card
   normal ?

5. Does anyone know how to write an international keyboardhandler ?

It's the way morley do it - obviously they execute a dir or similar command
to mount the disk, whereas the best way of causing filecore to mount the
disk but not set the CSD is to do something like read the attributes of
the $ directory object (what our filers do). I didn't know the morley
software did it, I'll shout at Gary today, I have to call him anyway....

>5. Does anyone know how to write an international keyboardhandler ?
I believe acorn released something like !IKHG which was a complete set
of utils to build keyboardhandlers. Acorn?

Yes, have you got a lot of TeX experience and two months spare?

You have to effectively turn TeX into a postscript version of TeX (actually,
it's worse than that because you don't have the full postscript font
layout - you have to turn TeX into an ISO8859/1 version of TeX) which
will take you a month, even starting with something like PSLatex,
then you'll have to modify the previewer.  This is actually the easier
bit because the previewer already uses native fonts (the approach I took
was to convert the TeX fonts to RiscOS rather than use a traditional
TeX bitmapped previewer).  You'll have to hack a IntMetrics->tfm
converter too.  But it can be done.  I'd say two weeks if you're keen.

Good luck.
