Demonstration Applications


INTRODUCTION
------------
As a brief introduction to this technology, the WLO mapping-layer is
comprised of a set of dynamic-link libraries (DLLs) which map Windows
API calls to OS/2 API calls at run time.  This DLL layer operates
like having Windows sitting on top of OS/2 PM and enabling relinked
Windows applications to run side-by-side PM applications.  WLO is
required for Windows applications to run on OS/2, in this manner.

This demonstration includes the Windows Accessories, or "applet" programs,
which have been relinked to run with the Windows Libraries for OS/2 (WLO)
version 1.0.  They are for demonstration purposes only and have not
been officially tested or released, but are meant to show how well the
WLO mapping layer technology works.  These accessory applets will be
familiar to any Windows 3.0 user.

A major feature of WLO 1.0 is that the versions of these Windows
accessory applets run binary compatible on either Windows 3.0 or
OS/2, meaning the same .EXE files can be used on either platform.
WLO operates on OS/2 versions 1.21, 1.3, and later.  The WLO DLLs plus
all of the Windows applets occupy approximately 2.4 MB of hard disk
space, after installation.

You will need to download the WLO10.ZIP file, which contains the WLO
DLLs, a small setup program, and the Windows 3.0 accessory applets.


IMPORTANT NOTES
---------------
WLO 1.0 coexists with the official released version of WLO 0.9, only
(1/26/91).  If you are running with a WLO version later than 0.9,
than you will need to either 1) install the original WLO release 0.9
DLLs, or 2) obtain a relinked version of your Windows application
compatibile with WLO 1.0.

The version of the Windows 3.0 Accessory Applets distributed on
Compuserve in May/91 were using an advanced version of WLO 0.9,
i.e. not the release WLO 0.9 libraries.  Therefore, you will need
to remove these applets from your OS/2 machine before installing
the WLO 1.0 versions contained on this disk, in order to avoid
experiencing any unexpected behavior.  Do this by first shutting
down all running applets, removing any references to these applets
in STARTUP.CMD, and rebooting the system to ensure that the WLO DLLs
have been properly unlinked.  Next, delete the *_B.DLL files (WLO
mapping layer, and the C:\OS2\DLL directory.  Finally, delete the
Windows 0.9 applets from their directory.


INSTALLATION
------------
The following instructions explain how to install WLO on a
hard disk and/or 3.5" 1.44 MB floppy.


    Hard disk installation
    ----------------------
    Create a temporary directory on your hard disk.  Make sure you
    have at least 1.5 MB free disk space.  Copy the .ZIP file into
    that temporary directory.  Use PKUNZIP with the -d parameter
    because the .ZIP file contains subdirectories.  The following
    commands illustrate the steps to unzip the files:

        pkunzip -d wlo10.zip

    With all files unzipped, delete the *.ZIP files, and run setup,
    as shown in the following example:

        setup c:\applets c:

    The first parameter to setup is the destination path to copy the
    Windows applet programs to.  The second specifies the drive letter
    from which you are running setup.  Adjust the hard disk drive letter
    according to your individual scenario.


    Floppy disk installation
    ------------------------
    Unzip the files to floppy disk to make it easier to install these
    applets on different hard disks.

    Create a temporary directory on your hard disk.  Make sure you
    have at least 1.5 MB free disk space.  Copy the .ZIP file into
    your temporary directory.  Place a blank 3.5" 1.44 MB floppy disk
    into A: or B:.  Use PKUNZIP with the -d parameter because the
    .ZIP file contains subdirectories.  The following commands
    illustrate the steps to unzip the files:

        pkunzip -d wlo10.zip a:

    Use setup in the same manner as in the hard disk installation,
    but with the drive letter of the floppy drive.  First delete the
    .ZIP file, then type the following:

        setup c:\applets a:

    The first parameter to setup is the destination path to copy the
    Windows applet programs to.  The second specifies the drive letter
    from which you are running setup.  Again, adjust the drive letters
    according to your individual scenario.


Be sure to read the README.TXT which will be copied to the destination
directory where you install the applets.  It will contain any additional
information you will need to know to use WLO.
