I will re-read the existing collision rules (maybe others can pitch in here). But perhaps we can say that roll-up regions must be addressed by line (which is only sort-of a cop-out). > > Not supporting % would certainly simplify things a great deal. I take it that 708 does not require vertical positioning within a region with %? Correct, 708 addresses a 'character buffer' which is indexed by line and character position, and the buffer is then rendered. roll-up happens when a carriage-return is written into a region that has roll-up behavior. > > -- > Simon Pieters > Opera Software David Singer Multimedia and Software Standards, Apple Inc.
