Thanks works.

The interface i a little bit funy but look very mutch
like the try...catch construct of java.

;; creating an intecepting an exception
(call-with-current-continuation
   (lambda (exit)
      (handle-exceptions exn
         (begin (put-line "Went wrong") (exit exn) )
         (put-line "Expression 1")
         (abort 'x)))
)

Java:

try {
   Expression1
   throw ..
}
catch(Exception e) {

}

I can even use vectors or records to build exception types. Fine! Only
this  call-with-current-continuation is clumsy.
