They are too old for that : feature to work. It works on newer BSD systems, and systems based on SVR4, : but not on the old beats I have here. I know that at least one debugger on SunOS 4 could attach to an arbitrary pid and tell you where it was. I thought that gdb could do that as well.... Warner
