SIGKILL is routinely used from command lines as an unconditional cancel, because SIGKILL can't be caught. Don't trouble yourself with writing a handler for it.
And there's this strange escalation of MVS operator commands. At first, the S222 from a CANCEL command couldn't be caught. But someone saw a requirement to catch CANCEL (what's wrong with MODIFY or STOP?) So, now S222 can be caught. So they had to invent FORCE for programs that ignored CANCEL (and other reasons). FORCE can't be caught. I'm waiting breathlessly for the next round. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
