Its really dependant on your setup. If you have SAS locally installed then sysuserid will return the username it gets, probably Windows user login (I can't test this). If you have it on a virtual system then it may be the login information for the virtual system. We have ours on Citrix and that return the user information which is setup in the initiation files. Depending on your setup and what you want to do, you would need to talk to your IT Helpdesk. Principally, you need to be careful what you are doing with the information, but also your IT will be the ones who deal with login information. If its just a matter of you want in your program and audit of who ran a program, then just setup a small dataset somewhere with user list and take it from there based on the sysuserid.
