> I'm sorry, I'm real stupid, what's tokenization?? The calculators change commands and such to single-byte tokens for ease of interpretation, speed, and somewhat size. That's why there's a big delay the first time you run a program after you edit it on the TI-85 and TI-86. The TI-82 and TI-83 tokenize the programs as they are written so there is no delay. (I don't know anything about 92 tokenization.)
