VDOS is the first DOS to support the Vortex format which become a standard format later on.
== Germanized-English RSX Commands in German and English; VDOS differences compared to AMSDOS ==* Some commands are available in German and English language. This is an advantage when using more than one DOS ROM at the same time.* Vortex apparently considered the is a German company, so they added RSX commands in German and English language. The normal AMSDOS RSX commands |TAPE.xx and |DRIVE/|USER too difficult for german users, and changed them to were added as |CAS and |SELECT (which resemble equivalent german German words ''Kassette'' and ''Selektieren''). This is making VDOS slightly incompatible with AMSDOS and all other AMSDOS clones (except for Also Dobbertin's X-DDOS, which does supports both the english English and germanized dialectsGerman languages).
|SELECT is used to both select user and/or drive. e.g. |SELECT,"3" for user 3, |SELECT,"B" for drive B, |SELECT "4B" for user 4 on drive B. VDOS doesn't have USER or DRIVE commands.
* VDOS will autoboot a file called "HELLO" if it exists on the disc. AMSDOS doesn't have this.
