My direct involvement with DECdtm ended in 1991, shortly before I returned to the US from my first UK secondment. However, I worked to stay aware of what was going on with it until I left Compaq in 1999. I can say that there are no technical reasons why it shouldn't support XA/TIP/TCP, and have been none for years. As for it being hard to upgrade, no I'd not heard it. I was not asked about this before I left Compaq in Feb 1999, and I've obviously had no conversations on matter since then. While I strongly disagree with their conclusions, I have no information for making any suggestions as to why they reached that conclusion, or even who 'they' are. I also have no current knowledge as to who may or may not be maintaining it. However, returning to Richard's first question: If Compaq VMS has interest in hiring Software Exploration to do this work, I would be extremely interested in talking to them about it. Tell me who to contact to deliver that message directly and I will. Finally, the 'VMS brains trust' may well have other reasons for pushing an RTR-everywhere solution. I have no reason for questioning that. I can just say with some high degree of confidence that the inability to adjust DECdtm for XA, TIP, and TCP is not technically justified. Jim.
