Tips:Use the BETWEEN-AND Operator to Search an Inclusive Range of Values
The BETWEEN-AND operator can be used inside of a where statement to determine if the value of a variable is contained within an inclusive range:
proc print data=sashelp.retail; where year between 1980 and 1984; run;
Notice that the boundaries that you give are always included in the range, so in this case the data from 1980 and 1984 is printed, along with data from 1981-1983.
