This file updates the following product:           
           
                NS/ODBC
                Version 5.11         
           
You should keep a copy of this Readme file as a reference.  Updated
information in this Readme file includes the following:
           
1. Installation Options
2. Hardware Requirements
3. Software Requirements
4. List of Files



Installation Options
--------------------
Our standard products offer three installation options:  Single User
Installation, Network Installation, and Shared Access Installation.
NS/ODBC does not specifically offer these options during installation.
If you use the NS/ODBC setup, you will essentially get a Single User
Installation.

But the NS/ODBC program files can be copied to a network drive (i.e.,
n:\path where n is the network drive and path is the network install
directory.  Once the NS/ODBC program files are copied to the network
directory, network users can run SETUP.EXE from that directory.  This
process is equivalent to a Network Installation.

Shared Access Installation is a network installation where all users
share product system files from a centrally-located network drive.
This is not supported by NS/ODBC since its program files cannot be
shared.  They fundamentally must be located on your local drive to
function.



Hardware Requirements
---------------------

AS/400 host requirements are:
     
IBM OS/400 Operating System V2R2, V2R3, V3R0M5, V3R1 or higher.



Software Requirements
---------------------

IBM PC Support/400 or Client Access/400 DLLs

The PC Support/400 and Client Access/400 Windows Application Program
Interfaces (APIs) are implemented as a set of dynamic link libraries
(DLLs).  A DLL is a set of routines that are bound to the application
at run time rather than at link time.

For NS/ODBC to function properly, the PC Support/400 or Client
Access/400 Windows DLLs must be located either in the \windows\system
directory, or in any directory contained in the DOS environment
variable PATH, or in the directory containing currently executing
application program.

The following DLLs are required by the NS/ODBC driver:

	- EHNAPPC.DLL    Router APIs
	- EHNRTRW.DLL    Router APIs
	- EHNSRW.DLL     Internal APIs (*)
	- EHNDQW.DLL     Data Queues APIs (**)

(*)  Only necessary to run remote commands on the AS/400 from ODBC.
(**) Only necessary to run data queues procedures. 

By default, the above DLLs are copied in to the \PCS directory by the
IBM PC Support/400 setup program (when installing IBM PC Support/400
for Windows) or in to the \CAWIN directory by the IBM Client Access/400
setup program (when installing IBM Client Access/400).


NetSoft NS/Router

For the 16-bit router:

	- EHNAPPC.DLL    Router
	- EHNRTRW.DLL    Router
	- EHNSRW.DLL     Transfer (*)
	- EHNDQW.DLL     Data Queues (**)

(*)  Only necessary to run remote commands on the AS/400 from ODBC.
(**) Only necessary to run data queues procedures. 

Note: If you want to use the NS/ODBC driver in read-only mode, when
      creating a new data source you should make sure to check the Read
      Only check-box.

Note: When configuring NetSoft NS/Router 16-bit, a configuration file
      is saved in your \windows\system directory (*.RTR). In this file,
      there is a parameter called PeekMessage. You should set this
      parameter as follows:

                         PeekMessage=0

      If this parameter is set to 1, you may be troubled by an
      unrecoverable system error (General Protection Fault).


     
List of files
-------------

NS/ODBC 16-bit copies the following files into your \windows\system
directory:

    - CTL3DV2.DLL
      Note: Due to known problems, this file should only be installed
            in the \windows\system directory.  Future releases of
            CTL3DV2.DLL will solve the problems.
    - HS400EXT.DLL
    - HS400STP.DLL
    - HS400.DLL
    - HSALIAS.DLL
    - HSDRDA.DLL
    - HSXFER.DLL
    - ODBC.DLL
    - ODBCINST.DLL


NS/ODBC 16-bit copies the following files into your \windows directory:

    - SDK400.EXE
    - SDK400.HLP
    - HS400STP.HLP
