[SOLVED] Re: Y-coordinates don't work in offset function

[Jonathan Kulp]

Many thanks, Trevor and Gilles!!  Both of those solutions work 
perfectly.  Now the question is which one uses the syntax that would be 
most appropriate to appear in the GDP docs.  My instinct is to use the 
one with #'(0.0 . 0.0) for the coordinates, since this is how I've seen 
X-Y coordinates specified most often.  Graham, do you have a preference?

Thanks again!
