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.
