To set up your SAS image to test in the Year 2000 time frame, you must install 3 new SAS modules and execute a PROC DATECHG data stream, similar to a PROC SETINIT. The modules can be downloaded from our Web site, and the PROC DATECHG stream can be obtained from SAS Institute Technical Support. Once you have installed the modules and run the PROC DATECHG stream, you will be able to run your current version of the SAS System with your system clock set to a date in the future or set to the current date.

These instructions describe how to download and install the 3 modules.

SPECIAL NOTE: AS WITH ANY SYSTEM UPDATE, WE STRONGLY RECOMMEND THAT YOU HAVE A SUCCESSFUL SYSTEM BACKUP OF YOUR CURRENT SAS SYSTEM BEFORE PROCEEDING WITH THE UPDATE.

SAS System Prerequisites for new modules

Before you attempt to install and run the new modules, you should ensure you have the following version of the SAS System:

Operating System	SAS Release	TS Level
AIX	6.12	TS045
HPUX	6.12	TS045
Sun4/Solaris2	6.12	TS045
Digital UNIX	6.12	TS040

Downloading the Modules

First, you must download the specific tar file with the 3 new modules from either the SAS Technical Support web site or from the anonymous FTP site.

1. To download from the Web site, click on the appropriate link below:

   UNIX Platform and SAS Release	Tar file URL location
   AIX 6.12 TS045	datechg.ar2.tar.Z
   HPUX 6.12 TS045	datechg.hp8.tar.Z
   SUN4 6.12 TS045	datechg.slx.tar.Z
   Digital UNIX 6.12 TS040	datechg.alf.tar.Z

2. To download from the anonymous FTP server, issue the following commands:
   • ftp ftp.sas.com

     Userid: anonymous
     Password: your_email_id

   • cd techsup/download/blind/datechg/platform

     Valid directories for platform are:

     1. solaris for the Sun4
     2. aix for IBM's AIX
     3. hpux for HP
     4. digux for Digital UNIX

   • binary

   • get datechg.platform.tar.Z

     NOTE: The platform specific file name can be found in the chart shown above.

Once you have downloaded the compressed tar file, follow these steps to uncompress the file and move the new modules into the correct location:

1. Change directory to your SAS installation directory, (also referred to as !SASROOT):

   cd /usr/local/sas612

2. mkdir year2k
   cd year2k

3. Copy the downloaded file into this year2k directory
4. uncompress datechg.platform.tar
5. tar xvf ./datechg.platform.tar
6. You should now have 3 new modules, named:

   sas_y2k, sassetin, sasdatec

7. Change permissions on modules for execution

   chmod 755 *

8. Now, set up a special configuration file so these files can be found in the SAS search path:

   cp ../config.sas612 ./config.sas612.year2k

9. From now on, when you want to run SAS with year2k modules, you will be required to add this option to your SAS invocation:

   -config !SASROOT/year2k/config.sas612.year2k

10. Also, you must edit this new config.sas612.year2k file and add one -PATH statement. Once you are in edit mode of the config file, find the series of -PATH !SASROOT statements. You MUST add the following line so that it will be the VERY FIRST -PATH statement in the config file. This is CRUCIAL!

    -PATH !SASROOT/year2k

11. Finally, you must "patch" this new sas_y2k file with the current !SASROOT value used for your current installation. First, cd back to the original !SASROOT location:

    cd /usr/local/sas612

    ./utilities/bin/patchname ./year2k/sas_y2k /usr/local/sas612

Running the new modules

The setup of the modules is now complete. If done successfully, you should now proceed to the application of the new PROC DATECHG stream which will be provided by Technical Support in a separate fax or email. Once the PROC DATECHG stream has been applied successfully, you can then set your machine date into the Year 2000 and invoke SAS via:

/usr/local/sas612/year2k/sas_y2k -config !SASROOT/config.sas612.year2k

With this setup, you can still use your same SAS directory setup for Year 2000 and non-Year 2000 invocations. The key is the new SAS module sas_y2k and the special configuration file config.sas612.year2k that was just created.
