{{omit from|J}} This isn't a J issue, it's an OS issue. Thus, for example, we could use <code>2!:0'xrandr -s 640x480'</code> on an operating system where that provides meaningful behavior. And, we could use <code>shell'mode CON: COLS=40 LINES=100'[require'task'</code> on an operating system where that provides meaningful behavior (and <tt>2!:0</tt> does not work on windows -- on linux this <tt>shell</tt> command is equivalent to <tt>2!:0</tt>). But these won't work in the general case, and it's probably best handle such tasks before starting J.
