Do you have to or nothing works, or you just do it as habit (like I do 
on occasion)? ' r ' is already a pointer, so I would think that

bool = fn SectRect (@testRect, r, @rIntersect)

...would work.

Otherwise, try

bool = fn SectRect (@testRect,#r, @rIntersect)

Otherwise, RP will say, no, that's wrong. :)

I don't even think I use @ with mine. FB seems to pointerize whatever 
the current need is automatically.

bool = fn SectRect (testRect,#r, rIntersect)
rc
