Let's see if the second time it works :-) GET MANX 3.60a.

3.60a includes a UNIX-like signal call that can trap the following:

divide by zero and overflow (SIGFPE)
illegal instruction (SIGILL)
illegal address or bus error (SIGSEGV)

As under UNIX one can trap and jump to a function, or terminate the program
(SIG_DFL) or ignore the trap (SIG_IGN).   The function can execute exit(),
longjump(), or return.  The last case will resume the program at the point
of interrumption.

Does this suit you?
