That is not clear at all. For example Focus and similar 4GL systems are FAR more expensive than COBOL development systems on a cost per seat basis, often by a factor of 10. Statements like the above are often made as though they are tautological truths, but they are not! Larry says "I note with interest that the ACT GNAT web pages indicate the forthcoming Alpha (only) VMS port requires VMS V7.0. Although I use it as a developer, I have never heard of anyone using VMS V7.0 (yet) in production. I know a large C-shop using VMS V5.4A on a cluster of 9 VAX systems for development." There are two separate issues here which are a little mixed up. First, is there really a market for a VMS port for VAX. It would not take much of a market to make it worth our while, but it is not clear that even this small market exists. So far, of the possibly VAX interested customers, none has been sure of whether they would be interested. Some VAX projects are base lined on Ada 83 anyway, and there is no point in changing. Others are planning on moving to Alphas soon anyway. If there is a sufficient customer base to support VAX/VMS, it is certainly a technical possibility The other issue is VMS 7.0 on the Alpha. Actually, we have had more trouble with not (yet) supporting 7.1, than with users who are not planning to switch to 7.x yet. There are good technical reasons for not choosing 6.3, since getting the tasking to work on 6.3 would be very much harder, due to the less developed state of the threads libraries. The users who have been interested in this product are generally planning to use 7.x for future production (which is what is interesting for a future product not yet released!) It would certainly be possible to generate a limited capability 6.3 release if there are interested customers. As always we find we are more interested in messages that say "if you had x, we would use it", or "we need x, please do it", than the style of messages which say "I am sure that if you did x (which I would like to have free), I am sure others would buy it" :-) P.S. we are planning an Alpha/NT release of GNAT, but so far we do not have firm plans for PowerPC/NT, since we have had no customer interest in that port. A status report on the VMS port incidentally is that it is about to go into field test phase two in a week or two, so the product release is probably a couple of months off (we plan a full 2.0.1 validation first).
