Snarf has been updated and should now work with old ATI graphic cards. Snarf is a TSR program that takes snapshots of virtually any DOS graphic or text screen. It's particularly useful under Windows XP, which does not capture DOS graphic screens. Although Snarf is not an XPL0 program, it's so useful that I couldn't resist making it available. It's 100% assembly code, and the source (of course) is included.
