What do these two statements Do WITHIN SAS macros? Can these statements be used outside of Macros? Again, is there a helpful site that breaks things down well? I'm still feeling really lost in the SAS pages online.
You have received poor guidance. Macro language is not something you should spend your time on, when you are a new SAS user. If you would like, I can give you a dozen topics that would be a better use of your time.

DO is to control code in a datastep and certain computation blocks in procedures such as Proc Report.
