Ctrl+z is the way to get out of top on HP-UX? It's not 'q' like any other top? In most terminals/shells, 'ctrl+z' is the suspend key, which sends a SIGSTOP to the process. This suspends the process - it doesn't terminate it. Suspending means the process no longer gets a timeslice on the CPU - and will last until the process is killed, or a SIGCONT.
But regardless, if you run top as system "top", it ought to be running in the foreground, and all keyboard input should be directed to it. So, if indeed, on your system, 'ctrl+z' isn't the suspend key (check stty -a), but the normal way to stop top, it ought to work. | [reply]

Unless your stty settings are all messed up very different from typical, C-z is not how you get out of top. As mentioned previously, 'q' will quit top, and batch mode with the number of iterations flag is the "correct" way to do it. See man top at a command shell for details, or check the matrix (pdf - witw) for where hp has them shuffled away at this point in time.
