Here is the function I use: Yes, I ended up doing something using the PID. But then most library functions are a SMOP; it still seems reasonable to provide the ones that users are going to need. At least you and I needed this one. | > it's neither pleasant nor efficient to always have to worry | > about signal exceptions popping up. | | Shall I read this as ``I use (try ... with _ -> ...) all the time because | I'm too sloppy to figure out exactly which exceptions I should trap'' ? | That's a dangerous thing to do, since any heap allocation can trigger | the Out_of_memory exception. That's an all-too-accurate reading! Except that I could perfectly well have a common exception "MYERR" and just use "try ... with MYERR(_) -> ...". I wouldn't object to the extra typing, but I guess it would be significantly less efficient. Is that true? I suppose I could try it and find out. | > (3) Is there some hook to allow a user-defined function to be called after | > the evaluation and printing of each toplevel phrase?

Well, since you excel at reading between the lines, you can read my question as "what a great idea it would be to add some hook... wouldn't it?" My guess is that it would be easy for a CAML-Light expert to add, since the interpreter's read-eval-print loop itself seems to be written in CAML. Cheers, John.
