Green Flag to switch on; Stop to switch it off. About to see information about MitDOS 3.1. Files or My computer to see files like songs. Control Panel to change settings. In calculator write things like 2+3 without spaces, or sin60. In translator.exe (Command Prompt) write first the language and then the phrase or the sentence to translate. MitDOS-Executive (Command prompt): Write “cls” to clean the screen. Write “cmd” to go to the main command prompt (to stop using functions like the calculator or the stopwatch). Write "help" to see all functions. Write "notes" to take notes. NOTES: Write something, use arrows to edit and X to erase a letter. Remember to click "Save" before clicking the top of the window (you do this to close all apps and go back to the home) and name your .txt file (you can't name a file with no words), so you can save and search it into My Computer (from here, searching the name of that file, you can edit it again, clicking "Save" and naming it with the same name, so as the item of your text in the Files list will keep the same name but changing the content, without saving another .txt file).
