Two things tend to disrupt console-watching execs: 1. You hit enter while in CP SLEEP. The SLEEP command ends too soon. If you need your exec to differentate between ENTER and timeout, use the ATTN option on SLEEP. You get RC=1457 if someone pressed ENTER. 2. Using WAKEUP and not checking for RC=6 (console input) and dealing with it. I recommend putting your scripts over in your Linux guests and drive them when ctl-alt-del is hit (entry in fstab). That script will run when you target the guest with CP SIGNAL SHUTDOWN, you FORCE it, or you LOGOFF the guest. Alan Altmark z/VM Development IBM Endicott
