Why? What are you trying to solve? Or, rather, what are you trying to break? In short - no. You stop the application [1]. >The dataset is users one and for some reason I would like to know if we can >Dynamically remove it from allocation. Stop the holder of that dataset and upon cleanup the dataset will be released by the system. Use D GRS command or ENQ in ISRDDN to see who is holding your dataset and how. Then you stop these ENQ holders. As others said about FREE=CLOSE, in REXX you do a ALLOC, do stuff, then a FREE. As others said, perhaps (?) with an APF-ed program standing outside the ENQ holder address space, you can do 'tricks' at your own career ending peril and serious data loss. Groete / Greetings Elardus Engelbrecht [1] - Or you give a command (if so programmed in the first place of course, say in a menu item or inside the program logic) to do a FREE. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
