Old version of SAS

Question

I am getting funky results in several ways (Like jibberish..almost like when opening a word document the wrong way). I am told our company is running an old version of SAS. it runs in a VMS environment. Can SAS "break down so to speak", where one not only gets jibberish, but basic logic statements fail work in an environment that where the SAS version is outdated, so to speak? almost as if something has become corrupted. Not sure if my question makes sense. I am not a techy person, so I do not know the language of IT very well. I can only program. anyway, does anybody have any experience with anything like this? thanks John
