Invoking a single (main) thread is appropriate for Notification from slave threads when the job is done. But we are far from that. We cannot even initiate several slave threads. The idea is to be able to run several J code units simultaneously in the same (OS) process (not different processes). Such facility is threads. Because J instance is not re-enterable from different threads, as shown, we need different J instances, one per thread. To start a thread, we need a callback: different callbacks (call addresses) for different thread-instances. But cdcb returns the same address from different J instances allocated in one process. Good to hear what solutions are proposed. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
