### 16.14 HOST

         HOST.
         HOST COMMAND=['command'...].

`HOST` suspends the current pspp session and temporarily returns control to the operating system. This command cannot be used if the SAFER (see SET) setting is active.

If the `COMMAND` subcommand is specified, as a sequence of shell commands as quoted strings within square brackets, then pspp executes them together in a single subshell.

If no subcommands are specified, then pspp invokes an interactive subshell.
