- ATARI: ABSOLUTE BEGINNERS COLUMN
- by Lew Stone from DISCOUNT COMPUTERS
- (GAG)
-
- If you use a disk drive, you are using a DOS (pronounced DAWHSS), the first
- letters of the words "Disk Operating System." Most computers don't work too
- well without a DOS. You can't save a program to a disk without it. Neither
- can you make backups, call up info from a disk or format a disk. If you
- ignore DOS, your computer will ignore you.
-
- When mini-computers were first introduced there were a lot of 'bugs' in their
- DOS. As newer editions became available, there were fewer and fewer 'bugs' in
- the operating systems.
-
- The older DOS would place info on a disk using fewer tracks made up of fewer
- sectors each. As better media became available, the newer DOS became
- available that would squeeze more sectors onto a track. You could run the
- older programs if you did some disk swapping.
-
- Almost all Atari 8bit disks come with a DOS already on it. The major
- exception is a 'data' disk. Sometimes, a non-standard DOS is used and the
- usual DOS commands will not work. Most IBM computers have a separate disk for
- DOS which has to be used before a program is loaded in. In general, the Atari
- is more user friendly than such a system.
-
- Each DOS has its own commands which are reserved words that have a special
- meaning to that DOS. Examples of some of the more widely used commands are
- CATALOG or DIR to get a listing of what is on the disk, SAVE to store a file
- on the disk, LOAD to load a copy of a file from the disk into the computer's
- memory, DELETE to remove a file from the disk, and FORMAT or INIT to prepare a
- disk to be used on your computer (use these two commands with great care.
- Either can destroy a good disk).
