What is DOS89?
----------------
Basically this is a DOS (Disk Operating System) program for the TI-89. It helps you manage your files without having press buttons etc. everything is run from commands that you type in for it to do. It is mainly for people who work on the Virtual TI, because it is very inconvenient to keep having to click the buttons and type at the same time in Virtual TI. You run dos and you can do everything with commands to manage files, run programs, etc.
