Once only, as far as I know - an AD/CD. Very unlikely to happen again, to judge from the strength of language used on IBM's web site: "The S/390 Application Development CD is a special packaging of S/390 software for the exclusive use of product development and support. It is restricted for use by qualified PartnerWorld for Developers members on S/390 development systems that were purchased through our program, or through approved IBM Business Partners that are fully authorized to sell the FLEX-ES emulator from Fundamental Software, Inc.. The S/390 ADCD software stack is licensed to the specific system by machine type/model serial number and cannot be transferred to any other machine. Use of the S/390 ADCD software on any other system or software emulator is strictly prohibited and is in violation of the terms and conditions of the loan." To all intents and purposes, it's not an option. Beware that making illicit copies of licensed software is a breach of the license agreement - one of the sanctions IBM (and/or any ISVs) has is revoking the original license. Interesting thing to have to explain to management. And 'disaster recovery' provisions _don't_ cover it. -- Phil Payne http://www.isham-research.com +44 7785 302 803 +49 173 6242039
