I would recommend going through a self-study course such as the UCLA website and specifically the SAS Starter Kit. If you learn better within an interactive environment, I would suggest checking out online course offerings such as the World Campus SAS courses offered at Penn State University (Stat 480, 481, & 482).
Update: Sorry should've read more carefully, I agree with @Christoper.Aden that there aren't really any equivalent languages with SAS. You can learn R to perform statistical calculations, but if you need to use SAS, then learning R will only be a small step in the right direction (general programming knowledge - the two languages are incredibly different in practice).
I would recommend getting an academic discount version of SAS if you enroll in a program like I mentioned above - Penn State currently sells a 1yr licensed copy of SAS for $30 (only to students).
