Hi Chris! The target is TSO, IMS, CICS. Thank you very much for your support, I will return to this questions in a couple of months with the right environment. Yes, we use TN3270 server in the z/VSE. If the problem comes again, i will trace and we discuss the problem again! :-) best regards, Norbert.
