I think the simpliest answer to this question is just plain NO. Granted, that technically it can be done, it is not something that your average application programmer would want to try. If something needs to be updated "ad hoc", then I'd suggest AMASPZAP. If something needs to be updated with any regularity, then I'd strongly suggest that an ESDS would be simplier to do than a PS file. The only minus is that an ESDS cannot be read as easily by an application as a PS file. Too bad IBM didn't make a "PS compatability" interface so that an ESDS could be read/written via a QSAM or BSAM DCB in addition to a DCB. I think that this is possible in z/VSE's version of an ESDS (but I could easily be wrong). -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
