My understanding is that this area will be used by VMS in case the system crashes. The contents of memory will be stored here. This is fine; but I was wondering if there are any ways to have this file/disk area serve two functions since it seems to be unused during "normal" VMS operations. For example, is there a way that it can also be a page or swap file until/unless the system crashes? Are there other uses or should I just keep my hands off? Thanks in advance to all who respond. -Ric Steinberger ------- first off, the file hase to be physical memory size plus 3 (to allow preserving the internal processor registers) leave well enought alone, as you would have to manually install the file after every startup - if you auto installed it, the system would come up, and start paging over your now quite valuable crash dump.
