It doesn't matter if it was an SVC 99 flag, the important aspect was that the realm of your question was "when I do a dynamic allocation". There's also a flag for JCL-based allocation (that will also work for dynamic allocation) but operates differently, and is located elsewhere (PPT, to be specific). Something like PPTNODSI (No DataSet Integrity), as I recall. For that one, the ENQ is first obtained, to ensure the dataset is indeed not being used in some conflicting way, and then released. -- Walt -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Re: What is the bit that causes the bypassing of dataset ENQ
I did not recall the exact operation of the bit flag. If I'd recalled that it was an SVC 99 flag rather than some sort of global flag I might well have found it myself. Why criticize people for asking a question? If they knew the answer they would not have to ask the question -- 'tis true.

It also would have helped if you'd said you were interested in -dynamic- data set allocation, rather than simply data set allocation.
