[..munched..] >I don t know if 3.o solves that kernel-bug. ( using 2.1 ) This is not a bug. All operating system kernels have resource limits. Congrats, You've discovered one of mach's. There's more than one way to kill a kernel by exceeding its limits, many I'm sure will remember that oldie but goodie "while(1) fork() ;". You have to program around these limits, you can't just claim its a bug and push it onto someone elses plate. I don't remember which header file contains a macro indicating the max number of threads per task, but I do know it exists ( anyone care to jump in with that info? ). >Post Post Scriptum : I think that NeXT should not publish files, which > will panic the system after inserting only one > character.

( See above ) Is it to late to have NeXT wipe the Examples directory clean in 3.0!!! And we must get rid of that nasty compiler, it could be twisted into a tool of system destruction! :-) :-) :-) -=Chris -- Christopher D.
