Rename is used to change the variable name, while label
option is used to change the dataset name.
For Ex:

data ds1 (rename=(sex=gender sal=income));
infile datalines;
input id name$ sex$ age salary;
datalines;
001 abc m 23 45000
002 def f 34 67000
003 mno m 21 36000
;
run;

data ds2(label=sample);
infile datalines;
input id name$ sex$ age salary;
datalines;
001 abc m 23 45000
002 def f 34 67000
003 mno m 21 36000
;
run;

Here label option changes the dataset name as sample. So
dataset will be as per label i.e. sample, but when we will
open it we will view as ds2.
