John,
If you're trying to change resolutions and use GEM with the 'new' res,
it can't be done without a reboot (well, desktop isn't happy, but some
things do work). If all you want to do is write your program in 80 columns,
then have the program switch you into low res to run, and then switch back
out when you're finished -- and as long as you don't mind dealing with a
slightly confused GEM, all you've gotta do is use Setscreen(-1l, -1l, 0);
to get into low res, and then Setscreen(-1l, -1l, 1); to get back!
