When I mentioned the selectedLoc funtion, I was forgetting about the
calculations to be done.
The selectedLoc returns the position from the left and top of the
card. Here is a script of how you might do this. It puts the text in
question at the top of the field.
put 8 into tMagicNumber -- see below
select line lineOffset(someString, field someField) of field someField
put the top of field someField into tTop
put the scroll of field someField into tScroll
put item 2 of the selectedLoc into tY
put tY - tTop + tScroll into tNewScroll
set the scroll of field someField to tNewScroll - tMagicNumber
tMagicNumber is to tidy it up. Without it, I find the text will be
slightly above the top of the field. This may be related to the field
margins, but I'm not sure. 8 seems to work (on Windows anyway).
As Scott mentioned, the new "formatted" properties in 2.3 look much
esier to use for this kind of thing.
