Since you're lecturing people who are attempting to help you, I should point out that you do not use DOS to edit files, and you did not do this in Windows 7 either. Typing Help there will list all the commands available.Īs I said in my post, this all shows my age! You'll find if you ask Cortana in WINDOWS 10 to find the DOS prompt it will do so and the DOS box opens on the screen in which you can type DOS commands. It doesn't draw pretty pictures on the screen! And the software I use to write my programs only works on DOS. To doing scientific work and complex calculations. I use a programming language called FORTRAN (short for Formula Translator) which has been around since the 1960s and is geared I still write computer programs for scientific work simply because there are no 'apps' available to do the things I want to do. Things like WORD, EXCEL etc nor did we have the internet. In those days, the only way to get a computer to do anything for you was to write your own programs (or 'apps' as they are now called) to do what you wanted. I have been using computers for scientific work since the 1970s. ![]() Basically they are commands that let you muck around with files - copy them, delete them, shift them to other 'folders' (which we called 'directories' in DOS) and WINDOWS allowed you to have several applications open at once and you could swap between them (it was like you were looking in to several windows, which is where the name came from).ĭOS commands are quite simple and a few things are still easier to do in DOS than in WINDOWS. Next big change and that started in the 1990s. Personal computers started to become available in the 1980s and most ran on DOS. It was the operating system for personal computers that Bill Gates invented originally and his fortune rose from that.
