The first is that it might be easier to write reports using Datacom/AD (SQL based) than "binary" information in a PDS. Most current programmers understand SQL better than any other "access" method. The second is that Datacom/AD is an RDMS. It __may__ have better error recovery and journaling than trying to do this in a PDS. An RDMS has built in concurrency. Just some thoughts as to a possible reason why. I may ask my manager. He's ex-CA and one original of the CA-11 developers. That is why the conversion was "no big deal" to us. -- John ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
