LWPD401A.EXE/binary

Contains the latest and final fixes for the LAN WorkPlace for DOS 4.01
product.  No further modifications to this version of LAN WorkPlace are
planned.  Customers are encouraged to upgrade to version 4.1.

Installation instructions:

Notes:

You must have the original LWP DOS 4.01 software installed in order to
apply this update.  If the patch program cannot find the original 4.01

The patch program will store the original files in the \XLN\PATCH\BACKUP
