| Huffman is quite nice. I did a model on my clac thayt compresse strings and made them 85% smaller regrdless of their composition. Only problem was that It only worked for character strings. |

If a byte is a byte in a string, in a program, in a group, or any other variable, your routine should work everywere meaning you should be as famous as Michal Vincent, Bill Nagal, Ben Illegbdu, Bob Marseah, Dan Englender, Scott Dial, and all those other important people.
I guess you wrote only a peliminarey model, however. |

| so what do you guys say, lets do it........ someone create a program that converts .txt to a ti app.......... i have the etexts ready to be converted........ |

Yeah, but we first have to figure out some form of compression.
One clarification, the ASCII table is AFAIK only 128 chars, which means that bit 7 is not used.
Maybe we could skip bit 6 like you suggested. Then we'd have 25% compression rate :)
Huffman is the most effective non-destructive algorithm. However, I'm not sure if it's suitable for such relatively small files you put on the calculator.

25% compression is still pretty nice. 
I figure 20,000 bytes of text would be the max amount. Would Huffman be effective for that size? |

| I can only speculate, but 20 KB of text can be compressed pretty well by using Huffman. |

Yea, Justin, what is this Propad thing you have been working on actualy do? Word processor?
I think the ebook reader idea is quite cool. Perhaps we could change movies too! Make an entire media player if you will. |

| Propad is a word processor program. You can get version 1.8 of it Here. It's a cool program. One question,how could you do movies? I mean, I know you can make some form of a movie,but could the calculator actually be able to handle playing movies? You would have to re-format them,of course,for the calculator,but is that even possible? |

| Not to mention movies would become quite large if they had any quality. |

| Yes,they would be pretty large. Also,I've seen some mini "movies" people have put on their calcs and they are really bad. You can't really make them out at all! |

The way I'd do it is making something similar to flash. Or more like a game without getting the user's input.
Just move some objects and use the calculator's functions to draw stuff like lines.
Like you first use lines to draw the horizon and some trees and then draw 2 stick figures moving towards eachother, draw some text balloons with text, and you have a simple movie. |

Yes, you can in fact. There are two main forms of movies on the ti. FIrst there are raw data movies. these movies can be compaired to Mp3's compressed but have raw moavie data. The other main form is more like midi. You have a library f textures that are included with the movie, and the move calls them in order and i form to form the animation.. If you say it looks crude, well you are usually right, however the important thng to realize its that there is basically no limit to the detail of the movie., It can look as good as yuou program it. and it takes little memory. It may be that is is comletely pointless, however we still need to experement to truly know the potential. |
