Using a single command block at a back of a computer, can you run multiple commands in 1 tick or below that even, and can you get an analog output from the sending the command? Can you get like a comparator output? Running a command such as /testfor can return a true or false value depending on if the testfor succeeded or not, this also works with all commands, is it possible for basically running a command to perhaps get a true / false value, like if cmdblock.runCommand("abc") then print("true") end.
