You can try getting the current font size, and then working out the
calculation yourself, but this is tough.  The standard font calls
don't provide all the information that really exists.

   #  process-name:  get the name of the current process
   #
   pst -c @
      | fpat '<active>' @
      | edstr -e 's/  */ /g' @
      | exfld -t ' ' $6

This works because the shell scripts normally run 'inprocess'.  Note
that it writes the process name to standard out, which you can
easily capture with 'active functions':

	proc := (( ^"process-name" ))

You can use it to set up your icon areas.  The problem is that most
interesting Apollo commands seem to clear the mark stack.

I remember a similar problem.  It seems that the 'interline font
spacing' is not available from any Apollo calls.  That was my
problem, at least.  Never did build up the nerve to read the font
files directly (where the information really DOES exist, see
EDFONT).

As an aside, it seems that X has a more complete model of fonts and
windows anyway.  I realize that X is not everyones answer
(especially in the sort term), but all the information appears to be
available.  You may be able to wait.

Except for that fixed size window problem.  I really wonder what you
are up to, and what the basis for you user interface is that
REQUIRES a fixed size window.  Anyway, X won't (easily) let you fix
it at a single size.  You must be prepared to run in whatever window
you get.  It is the USERS option to decide how much real-estate he
can dedicate to a single application.  (Sorry about the high-horse,
but @#$&*%&#$#!!)
