Hi Eric - I think you can probably get what you want as far as the first
part of your request goes by fiddling with the textShift property. Set
your textsize first, then your textHeight and then set the textShift to
something like -20 (+ or - a bit) ­ i.e. (set the textShift of char 1 to
-1 of fld x to y ­ and you should be almost there.
