At the end of fall term, SAS 8.2 was installed on Oregon.
For most users, upgrading to the new version should be easy. However, if you're
among those who need to explicitly convert their older SAS version 6 datasets
in order to read them in 8.2, the task is a bit more complex.
For example, suppose you have two SAS version 6 permanent datasets called datafile1
and datafile2. To convert those datasets from version 6 to version 8.2, you'll
need to follow the steps outlined below:
1. Because both versions shouldn't be stored in the same directory, you'll
need to create an OpenVMS directory to temporarily hold the old format datasets:
$ create/dir [.old]
2. Move datafile1.* and datafile2.* into that directory by typing:
$ rename datafile1.* [.old]
$ rename datafile2.* [.old]
3. Using EVE or EDT, create a file called convert.sas containing the lines:
libname mystuff base '[ ]';
libname oldstuff v6 '[.old]';
proc copy in=oldstuff out=mystuff;
select datafile1 datafile2;
run;
4. Run the conversion job by typing:
$ sas82 convert.sas
5. Using EVE or EDT, check convert.log to make sure the job ran properly.
6. At a later point, after you have verified that your old data sets have been
correctly converted to version 8.2 format, you can remove the old format data
sets and the temporary directory you created to hold them:
$ set def [.old]
$ del datafile1.*.*,datafile2.*.*
$ set def [-]
$ set prot=o:RWED old.dir
$ del old.dir.*
