The hot fix package downloaded is a self extracting executable named 
81st01o2.exe which will install the following files:


      * sasttest.dll
             the replacement module containing the fix

      * 81st01o2.aud
             a hot fix identifier file which will allow Technical Support
             to determine which fixes have been applied to a system

      * 81st01o2.txt
             a copy of these installation instructions



IMPORTANT NOTES:

1.  You must have Release 8.1 TS1M0 installed on your system before 
    applying this update.

2.  81st01o2.exe must be run from an OS/2 command-line and must be launched 
    from !SASROOT (the directory where Release 8.1 TS1M0 is installed).   



AFTER DOWNLOADING:

In this example, it is assumed that !SASROOT is: 
c:\sas


STEP 1
Change to the !SASROOT directory,
  
        [c:\] cd c:\sas


STEP 2
Move the downloaded executable to the !SASROOT directory.  Assuming 81st01o2.exe 
is downloaded to c:\myfiles, 

        [c:\sas] move c:\myfiles\81st01o2.exe \sas\81st01o2.exe


STEP 3
Back-up the original sasttest.dll,

        [c:\sas] ren c:\sas\stat\sasexe\sasttest.dll sasttest.000


STEP 4
Assuming you are still in c:\sas, launch the executable.
The "/directories" option is required to maintain the proper
directory structure during file extraction,

        [c:\sas] 81st01o2.exe /directories



This completes the installation of hot fix 81ST01 on OS2.
