It depends of what you expect of the 'xyloc' command. Should the x-setting persist or should it be set to '0'. And if so, when schould it be set '0'? If you want it just for the next object, than 'global positioned objects' might be better than a single command. An idea might be to leave the xoffset fixed after an 'xyloc' and only increase the 'y' setting according to the usual rules, effectivly defining a new column. > I've been intending to write such a new command as my contribution > to mgp, but just haven't found the time yet.

The 'heavier' part was the 'x' offset, because this is usually determined dynamically and no 'xpos' element exists within the render_state structre. 'ypos' exists an can be easily modified, as shown by the 'again' command. > > And while I'm dreaming of what I might contribute, I've also been > thinking of "%mark <a-z>" and "%again <a-z>" commands that allow > 26 locations to be stored and jumped back to. This is what I also thought of in one of my other postings. This command should store the x and y offset. > > Why: I wanted to write on all pages the theme on a fix position on the > > page.
