The metasyntax used in this manual to describe statements is explained in the manual “Commands” [8]. Operands reserved for privileged users are shown in the formats with a gray background.
Because the names are frequently mentioned, for the sake of simplicity and clarity the following abbreviations are used:
- BS2000 servers for the servers with /390 architecture and the servers with x86 architecture. These servers are operated with the corresponding BS2000 operating system. 
- /390 servers for the Server Unit /390 of the Fujitsu Server BS2000 SE Series 
- x86 servers for the Server Unit x86 of the Fujitsu Server BS2000 SE Series 
- SE servers for the Fujitsu Server BS2000 SE Series (Server Units /390 and x86) 
In the examples the strings <date>, <time> and <version> specify the current outputs for date, time and version of a software product when the examples are otherwise independent of the date, time and version.
