To turn it off create the environment variable KAIOOFF (most set this to '1' but it is it's existence that is important not it's value; if it exists KAIO is turned off). If I am wrong and the default is no KAIO, as on HP, then create the environment variable KAIOON to enable KAIO. These must be set in the environment that starts the oninit program. Art S. Kagel
