It's called BMP -- Batch Message Programming. Instead of going against the database directly, the Batch job talks to the IMS control region. My understanding (I am not an IMS application programmer, nor do I play one on TV) is that there is little effort required to convert Batch offline to BMP processing, but an expert would have to confirm. Also, there is the crude approach of processing against a copy of the database. If it weren't moribund, I would suggest posting the question on IMS-L. I have been a subscriber over there for years, since I have only (for three years) once worked at a non-IMS shop. I haven't seen a posting from it in a long time. - Too busy driving to stop for gas! ---------------------------------------------------------------------- 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
