You can't do that. You can only do: HLIN x1, x2 AT y or VLIN y1, y2 AT x And if you POKE 49234,1 you will get a full 40x48 screen of graphics. Do POKE 49235,1 to get the four-line text window back. There are a number of other "soft switch" locations. POKE 49236,1 selects graphics page 1 and POKE 49237,1 selects page 2. The last two are most useful in high-res mode, because low-res page 2 is the default starting location for BASIC programs. Incidentally, low-res and text modes use the same memory locations but interpret them differently. So of course there is a text page 2 but you still have to move your program to use it (just as with low-res page 2). To get out of the monitor: Ctrl-C Return - return to BASIC There are, of course, many other features in the ROM; it's just a matter of digging up the programming info. And (since you have such a late member of the ][ series) there are also features in the hardware, such as double- resolution text, low-res, and high-res modes, that the ROM was never updated to handle. However, you might try PR#3 and see if you get 80-column mode. -- Derek

The //e (I think it was the //e) first contained them. Every machine after that, including the //gs, contains them. The //gs also has its own modes, of course. I think you can get at the double-res graphics modes from BASIC, but there are no BASIC commands that directly support them. Also they use banked memory. You can get at the 80 column text mode with PR#3. I think I read on comp.sys.apple2 of demos that do that, but they were written by Bruce Tognazzini or Paul Lutus or some other godlike figure. :) -- Derek
