If false, not. This check is included in my DISK.COM and DISK_WATCHER.COM which have been submitted to DECUS tapes in the past, and are also available on narnia.memst.edu (141.225.1.24). They also handle shadow sets, which need to be handled similarly. Bound volume sets are not a special case. BTW, I discovered this by getting everything I could on a striped and a non-striped disk and comparing the two. The bit in DEVCHAR2 isn't documented that I know of, and may be subject to change. -- Harry Flowers Internet: FLOWERS@MSUVX2.MEMST.EDU Memphis State University & Bitnet: FLOWERS@MEMSTVX1
