U.S. Geological Survey Fall 1985 DECUS Symposium Menlo Park, California RSX SIG Tape Submissions We are pleased to present two modest submissions to the Fall 1985 RSX SIG Tape: ------------------------------------------------------------------ Name: VVC -- Volume Valid Control task Operating System: RSX-11M-Plus V2.1E Author: Gary L. Maxwell Version: V01 How to build: @VVC.CMD This task will bring a system disk "back to life" after losing hardware or software volume valid (whatever the reason). VVC stalls I/O to the system disk, while it waits for the disk to return to operating condition. What was formerly a fatal condition under M-Plus is now recoverable. Please refer to the source file VVC.MAC for implementation details. ------------------------------------------------------------------ Name: VINIT.PAT -- Patch file to Fortran-77 OTS Operating System: RSX-11M-Plus V2.1 Compiler Version: Fortran-77 Version 5.0 Authors: Gary L. Maxwell and Lawrence M. Baker Version: F7705Z How to build: See VINIT.DOC This patch fixes a bug in the Fortran-77 OTS which causes Virtual Arrays to fail in I/D Space tasks. Please read the accompanying Multi-Tasker article in VINIT.DOC for test case and build instructions. ----------------------------------------------------------------- Please report any problems or suggestions regarding this software to: Gary Maxwell U.S.G.S.
