Here are some tips for How to share your SAS knowledge with your professional network.
Hi User:Jpmeyers, I love how thorough the documentation and code are for %NEWSURV. I think the way you upload new versions with a date appended to the filename is fine. Another way is to take advantage of MediaWiki's version control. See the latest file you uploaded, File:Newsurv 08012016.sas. Note that there's a link to upload a new version. You could upload each new version to File:Newsurv.sas. It will preserve a time stamp, and the edit/commit message can mention the date, as well. You can easily link to the previous versions, as they are all saved.
