Level 3 is the early complete server (Level 1 was similar to shared DFS and Level 2 was a very basic server). It runs on a Master or a BBC micro with co-processor.
The server supports the standard manager's interface for operation codes 0 to 32. It also
supports the standard set of *commands (*Delete, *Dir, *I am, *SDisc et cetera).
It also supports several management commands which are detailed below:
*NEWUSER <username> Creates a user account for the specified username. *PRIV <username> [S or L or none] Sets the user privilege... System, Locked or Normal. *REMUSER <username> Removes the user account for the specified user.
Error codes and the Passwords file are the same as for the FileStore.
There are no further details on Level 3 available.
