I use PG to develop, so I don't exactly know how as it is all handled 
automatically.  However, if you don't want to use a PG edit field with a 
scroll bar grouped with it, you can get the height of the text and divide it 
into the height of your window/edit field.  For the text height, I use 
RowHt=USR FONTHEIGHT+3 in a program that has a grid and in which I need to 
set the scrolling.    The trick here is that in rich text, each line can be a 
different height.  Too much fussing for me.  I would think about looking at 
PG created or at least see how STAZ handles these things in the PG runtime.

If you do use a PG field, remember you have to add a Return  (chr$(13) ) to 
the field to "wake up" the scroll bars.

Hope this helps,

George
