      * 81ba34o2.txt
             a copy of these installation instructions; this file is installed
             in !SASROOT\core\sasinst\hotfix 


IMPORTANT NOTES:

1.  You must have Release 8.1 (TS1M0) installed on your system before 
    applying this hot fix.

2.  81ba34o2.exe must be run from an OS2 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 81ba34o2.exe 
is downloaded to c:\myfiles, 

        [c:\sas] move c:\myfiles\81ba34o2.exe \sas\81ba34o2.exe


STEP 3
Back-up the original file(s),

        [c:\sas] ren c:\sas\core\sasexe\sassfm01.dll sassfm01.000
        [c:\sas] ren c:\sas\core\sasexe\sasmeans.dll sasmeans.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] 81ba34o2.exe /directories



This completes the installation of hot fix 81BA34 on OS/2.
