Can I rename a variable in a SAS data set without input/output actions in data step, since I don't change the data stored in the set actually?

Yes, you could use proc sql instead:

 

proc sql; create table TEST as select

old_name as new name,

other_stuff,

more_other_stuff

from TEST;

quit;

 

Or proc datasets.

Doesn't this require the processing of every observation in the data step?

 

Or proc datasets.

 

I'm 100% sure this does not require processing of every observation in the data step. It doesn't even have to process one observation.

@Steve1964 No, you cant. As suggested by @Ksharp, uwing proc datasets is the most efficient way to solve the issue.
