Aside from the fact that sxt requires kernal support that not all SYSV machines have, *something else*, indeed. So long as you have ksh, whose sxt job control crashes machines, running under shl so that you can read a new .*rc file to give you the same? environment you left especially resetting terminal characteristics *AND* you don't really want to background anything *AND* you don't mind a maximum number of processes *AND* you don't mind several processes on your screen at a time (this is most fun when each sxt has different stty params), *T*H*E*N* shl is a fair surrogate for "real" job control. You still can't stop & restart a process. ALSO, shl cannot be started under shl nor can shl be used as a login shell. I put shl in my .profile & use ksh as shell for nearly everything that will take it immediately on a 3b2 and ksh alone on a 7300. Given a choice, I prefer ksh on 4.x. K. Richard Magill
