Mailarchives (A89: ti-89 video mem size)

I have a question about the video-memory on the ti-89. Now, the actual memory is the same size as the 92+ right? but only a portion of it can be seen. Does this mean that there's a whole lot of extra memory that can be used for variable storage? or is it somehow just omitted? One thing I noticed is that if you make a "hello world" program, but make the "hello world" string be very long like, "hello world, how are you today? I don't feel really well because I'm confused about ..." then it will wrap around the screen just like the 92+ would, but you wouldn't see stuff off the screen... I guess this means that when games and apps are being programmed specifically for the 89, you will no longer be able to use the video-mem like one big long chunk of ram. Now, it's a bunch of little pieces that are all cut up and separated :-( so wrapping will not be able to be used quite as easily (for instance with an asteroids game where the asteroids carry from one side of the screen onto the other).

"The greatest pleasure in yo-yoing is an abstract
pleasure--watching the dramatization of simple physical
laws, and realizing they will never fail if a trick is done
correctly. The geometric purity of it! The string isn't
just a string, it is a tool in the enactment of theorems.
It is a line, an idea" - Frank Conroy, Stop Time
