From: Dominic Dunlop <uunet!sphinx.co.uk!domo> [domo asks that you: Please observe Followup-to above. -mod ] Does anybody out there know if the venerable C-ISAM interface has been adopted, or is about to be adopted, by any public standards body (ANSI, ISO, IEEE, UL... you name it), or is specified as a requirement by any purchasing agency (NIST, CCTA, NASA...). (Yes, I know that purchasing agency is a loose term: I mean the kind of outfit which draws up specs which some large purchaser then makes binding on their suppliers.) As far as I'm aware, the current state of play is that C-ISAM has beached in the X/Open Portability Guide, but no public body has tried to pick it up from there. Oh yes. Might C-ISAM pop up in SVID 4? I seem to recall Informix (or RDS, as they were then) claiming to have sold technology to AT&T for a juicy sum a few years back, but have seen no obvious fruits. Clues or pointers, anyone? If your reply is as speculative as this enquiry, you might drop me mail. If, on the other hand, it's good solid dope, by all means post it straight away. I'll summarise to the net in any event. -- Dominic Dunlop The Standard Answer Ltd., using Sphinx' facilities (for which much thanks) domo@sphinx.co.uk Volume-Number: Volume 16, Number 53

X/Open has not beached C-ISAM, but has instead firmed up the specs. Quoted from the X/Open Portability Guide Issue 3 which I received about a month ago: The X/Open ISAM definition is a major subset of the specification of C-ISAM product, version 2.10, published by Informix Software Inc. of Menlo Park, California. In Issues 1 & 2, certain implementation specific features were dropped, for example, audit trail and decimal datatypes. In Issue 3, more detailed descriptions of locking and error handling were provided, as well as minor changes to accomodate ANSI COBOL standards. As far as I know, Informix has said that they will conform with X/Open, and other vendors are coming out with compatible versions of X/Open ISAM. -- Godfrey Lee P.O.

I just received some marketing material from Sun, and in one of the brochures ("The SPARCware Application Environment"), the mention that they now have an ISAM. No further details given. Is there anyone who knows anything more about this particular ISAM? Who makes it (INFORMIX, Sun, ...)? Does it conform to the X/Open spec.'s (I assume it does, although they doesn't say so)? -- Robert Claeson E-mail: rclaeson@erbe.se ERBE DATA AB Volume-Number: Volume 16, Number 55
