I didn't see the original post. What language? Enterprise COBOL makes this very simple because it can hide the details of dynamic allocation from the programmer. In Java, use JZOS and the zFile class to do all the difficult work for you. In assembler, you use BPAM. That entails OPENing the PDS as a PDS, doing a FIND for the member name, then doing a READ for each physical block of the member. Deblocking into individual records is done by the application program, not the access method. If you run your program under ISPF, then you can use the LM* services to do all the "fiddly" work for you. I don't know z/VSE, but I did a quick look at it. I don't know of anything as nice and easy as that in z/OS. -- 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.
