V4 used for that purpose a dedicated control character embedded in normal text in contrast to System 3, which extended the 574:). A command is defined by any procedure which is exported and has an empty argument list. Parameters to the command must be defined before executing the middle click, and must be explicitly scanned and retrieved by the procedure. No checks or questions occur during command execution. This is sometimes called a 1004:
network card. The basic system runs from one HD floppy disk, and more software can be installed through a network. The full installation includes the Gadgets GUI. It is written fully in the language Oberon. The latest available version was 2.3.7. It is dated 5. January 2003 and sometimes also labeled

Although very different from a command line, the TUI is very efficient and powerful. A steep ascent in the early learning curve makes it a bit difficult at first. No questions are asked: this is a deliberate design decision, which needs getting used to. Most editors ask the user when closing a
