(and it could be a file, if speed isn't important) that stores graphic data in the same manner as it would be if it was in video memory and being displayed on the screen. One way of creating that buffer is just to put stuff on the screen and then use GET to save the video data in an array (which is an area of memory). Another way is just to write data (e.g., POKE) to an array in the proper fashion. If you want to see a demonstration of how to do *that* (for any of the video modes that QB supports), you could look at

But if you're only interested in mode 13, things aren't near as cumbersome (and possibly slow) as those routines may make it seem.
