RRBROM INSTALLATION INSTRUCTIONS
                              Version 2.0  
                                12/13/95

     The Roanoke River Basin Reservoir Operations Model (RRBROM)
is a simulation/optimization model of the major impoundments on
the Roanoke River.  It operates on a daily, weekly, or monthly
timestep and runs in 32-bit mode under Windows 3.1 and 3.11 and 
under Windows 95.

     OS/2 Warp does not support the version of the Wins32s
package required to run RRBROM.  It is our understanding that IBM
is currently working on a maintenance release that should remedy
this situation and permit RRBROM to be run under OS/2.  

     The minimum recommended system configuration is a 486-class
PC with 8 MB of RAM and at least 20 MB of free hard disk space.

     Because the program runs in 32-bit mode, the Win32s add-on
package to Windows is required.  This feature may or may not
already be on your computer.  Instructions are provided below for
both situations.  If you are not sure whether you computer is
configured with Win32s, we suggest that you first install only
the model (RRBROM) and try to run it.  If you get an error
message saying that Win32s is required, simply follow the
instructions in Step 1.  You will not need to re-install the
model after installing the Win32s subsystem.


1.  IF YOU DO NOT HAVE WIN32S ON YOUR COMPUTER, follow these
instructions.

     NOTE: The Win32s installation program will copy the
     following files to your WINDOWS\SYSTEM subdirectory.  In the
     event that you ever want to uninstall the Win32s feature,
     you should determine prior to installation whether any of
     these files are already in your WINDOWS\SYSTEM subdirectory. 
     If so, make sure that you do not erase them when
     uninstalling the program.

     The installation program will also create and load a
     new WINDOWS\SYSTEM\WIN32S subdirectory.  

     a. If not already running, start Windows.

     b. Insert the Win32s installation disk.  

     c. From the Program Manager menu bar, select File, then
     Run.  In the dialog box that opens, type "a:\instl32s"
     (or "b:\instl32s" if b is the designator of your floppy
     drive).  (Do not include the quotation marks with these
     commands.)

     d. Follow the instructions on the screen.

     e. Edit the SYSTEM.INI file in the WINDOWS directory as
     follows.  Immediately after the [386Enh] statement add
     "device=c:\windows\system\win32s\w32s.386".  (Do not include
     the quotation marks or any blank spaces in this statement.)

     f. Proceed to Step 2.


2.  IF WIN32S IS ALREADY ON YOUR COMPUTER, follow these
instructions.

     a. If not already running, start Windows.

     b. Insert the RRBROM installation disk.  

     c. From the Program Manager menu bar, select File, then
     Run.  In the dialog box that opens, type "a:\install"
     (or "b:\install" if b is the designator of your floppy
     drive).  (Do not include the quotation marks with these
     commands.)
 
     d. Follow the instructions on the screen.

     e. If you wish, set up the program to run from an icon, as
     follows:
          
          (1) From the Program Manager create a new Program Group
          by selecting File, then New, then Program Group.  For
          the requested Description, type RRBROM. 

          (2) Create a new Program Item by selecting File, then
          New, then Program Item.  The Command Line requested is
          "..\RRBROM\RRBROM.EXE".  Click on Change Icon and enter
          "..\RRBROM\RRBROM.ICO" as the file name.
