As I remember you can do this with a shell wrapper and a carefully coded trap command. Interrupts are just that and will therefore never reach your EXIT PROGRAM. However, they are (or were) propagated back to the shell script. Don't trap too much otherwise the shell script will lock up. Sorry I don't have any examples.
