Dear Hans and others interested in this question, Further to Willi Brand's communication, I have seen a demonstration of Isodat NT, which was given to me at the recent SIMSUG meeting hosted by ITE Merlewood (Cumbria, UK). I think it looks pretty good and certainly worth waiting for. It's definitely an improvement on Crtl-Alt-Del Isodat5.1 under CDOS. In essence, it's a modular package that can be tailored by the end- user to his/hers own system configuration and individual requirements. So, no matter what IRMS configuration one can run everything from the same platform and merrily swap data. Rumours have it that it should become available in summer/autumn this year.
