If anyone took my statements above to imply that you could create a multithreaded app solely using modern RPG, that was never my intent. >From the Infocenter: The iSeries system now supports multithreading. ILE RPG does not directly support initiating or managing program threads. However, ILE RPG procedures can run as threads in multithreaded environments. If you want to call an ILE RPG procedure in a multithreaded application, you must ensure that the ILE RPG procedure is threadsafe. You must also ensure that any system functions that your procedure accesses are also threadsafe. Regards, Andy Nolen-Parkhouse
