PEEK/POKE Video buffer

PCOPY still works, though there's also a _COPYIMAGE routine now which you could make use of. 99% of the old QBASIC commands work exactly as they used to, with the main exceptions being the ones which relied on OS specific memory addresses and such (such as several of the PEEK/POKE calls), and DEF Fn, which hasn't ever been added to the language yet.
